Description

Technical Field

[0001] This invention relates to the field of mineral processing technology, and in particular to a process layout method for Nelson gravity separation of the entire grinding feed stream. Background Technology

[0002] In the field of precious metal beneficiation, especially in the recovery process of primary gold ore, Nelson gravity separation technology is widely used due to its excellent collection ability for free gold and coarse gold particles. This technology is based on the principle of enhanced centrifugal force field, creating a high-gravity environment through a high-speed rotating conical drum, allowing high-density minerals to rapidly settle and enrich in the flow film layer. In recent years, with the continuous development of combined grinding and gravity separation processes, the industry has gradually explored directly introducing the entire discharge stream from grinding into the gravity separation stage, aiming to reduce intermediate classification or screening processes, improve overall recovery rate, and reduce energy consumption. Against this backdrop, the process configuration of multiple Nelson concentrators operating in parallel has gradually become the mainstream choice for large-scale gold mine beneficiation plants, with the aim of increasing processing throughput and improving equipment utilization to meet the growing demand for raw ore processing.

[0003] In practical engineering applications, grinding slurry discharge typically exhibits characteristics such as strong flow pulsation, wide particle size distribution, and frequent concentration fluctuations, posing a severe challenge to the stability of gravity separation feed. If the feed share of each parallel unit cannot be effectively balanced and dynamically responded to changes in operating conditions, some units are prone to overload or idling, thereby affecting the gold particle collection efficiency and even causing concentrate loss. Furthermore, traditional discharge rotation strategies often rely on fixed time periods or manual intervention, lacking an adaptive mechanism coupled with the current collection status and material flow dynamics, making it difficult to guarantee optimal operating efficiency under continuous operation conditions. Summary of the Invention

[0004] In view of the aforementioned existing problems, the present invention is proposed.

[0005] Therefore, this invention provides a process layout method for Nelson gravity separation of the entire grinding feed flow to solve the problems of unbalanced feed distribution and lack of dynamic control of discharge rotation in parallel units.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention provides a process layout method for Nelson gravity separation of the entire feed stream in ore grinding. The method includes: collecting the discharge slurry from a gold ore mill and channeling it into the entire feed stream manifold; performing a slow-release distribution in the equalization chamber; simultaneously allocating branch share benchmarks and branch access order to generate a branch equalization feed stream set; sending the branch equalization feed stream set into a parallel Nelson gravity separator unit for centrifugal bed trapping and solidification, solidifying free gold, coarse gold particles, and high-density heavy sand in the gold ore mill discharge slurry into a stable trapping section, generating a parallel online operation diagram; and according to the... The system connects to the online operation chart, maintains stable anti-fluctuation share within the full material flow manifold, marks the ore-discharging units to be discharged in the current cycle, and generates a rotation ore discharge schedule. It then performs share-gradual transfer rotation ore discharge on the rotation ore discharge schedule, obtains gold concentrate batch entries, updates the share distribution entries of the branch balanced feed flow set, and generates an updated ore discharge operation chart set. Finally, it performs batch archiving and rotation benchmark write-back on the updated ore discharge operation chart set, merging the gold concentrate batch entries with the rotation ore discharge schedule set to generate a Nielsen reseparation operation record set.

All ore discharge collection entries are merged into the total material flow manifold, and inlet pulse merging is performed to generate the manifold inlet merged flow; The merged flow from the manifold inlet is introduced into the equalization chamber of the full-flow manifold, and short-cycle slow-release slicing and long-cycle slow-release convergence are performed sequentially to generate a set of slow-release distribution entries for the equalization chamber.

[0008] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for generating the branch-balanced feed stream set are as follows: Based on the equalization cavity slow-release distribution entry set, perform branch share benchmark freezing and branch access phase arrangement to obtain the branch distribution arrangement entry set; Based on the branch distribution arrangement entry set, expand the current share of the branch, obtain the share distribution entry, and perform share closure verification and gap backfilling registration to generate the branch balanced ore feed flow set.

[0009] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for centrifugal bed trapping and solidification are as follows: Establish a corresponding access relationship between the branch balanced feed flow set and the parallel Nelson gravity separation unit, and arrange them into a parallel access list based on the branch share benchmark and the branch access order; According to the parallel access list, the branch balanced feed ore flow is sent to the parallel Nelson gravity separator unit and loaded into the centrifugal bed. Free gold, coarse gold and high-density heavy sand are written into the continuous capture position status of the centrifugal bed, and the capture ready lock is executed to generate the capture ready list.

[0010] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for generating the parallel online operation diagram are as follows: Based on the capture readiness list and taking the continuous ore supply time window as the boundary, the stable capture section of the continuous capture occupancy status of the centrifugal bed is defined and registered, and summarized into a stable capture section list. Based on the stable capture segment list, the corresponding access relationships, branch share benchmarks, and branch access order of the parallel access list are bound to the start and end boundaries of the stable capture segment to generate a parallel online operation diagram.

[0011] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for maintaining a stable anti-fluctuation fraction within the entire feed stream manifold are as follows: Read the parallel online operation diagram and extract the access relationship, branch share benchmark and branch access order, merge them into a share reference table, perform branch access phase playback locking, and generate manifold maintenance input packet; The manifold maintenance input package is imported into the full material flow manifold. Long-cycle output segments from the equalization chamber slow-release distribution item set are sequentially used, and the share correction is performed in conjunction with the share reference caliber table to generate an anti-fluctuation share steady-state maintenance package.

[0012] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for generating the rotational ore discharge list are as follows: Based on the anti-fluctuation share steady-state maintenance package, the continuous ore supply time window of the stable capture segment is summarized, and the ore-discharging unit in the current round is marked. At the same time, the online set of parallel Nelson gravity separation units is extracted to generate the round pointing package. The round-direction packet and the manifold maintenance input packet are merged according to the branch access order, and the branch share gradual transfer starting caliber corresponding to the ore unit to be dispatched is written to generate the rotation dispatching list.

[0013] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for performing a share-gradual transfer of rotational ore discharge on the rotational discharge list are as follows: Based on the online aggregation of the ore-to-be-discharged units and parallel Nelson gravity separation units in the rotation ore discharge scheduling list, a share transfer association is established on the full material flow manifold side to generate a share gradual transfer execution list. The share gradual transfer execution list is executed with a share decreasing and increasing redistribution, and the take-up share of the corresponding branch of the mining unit to be dispatched is moved to the online set of parallel Nelson gravity separation units, generating share gradual transfer entries.

[0014] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for generating the updated set of the discharge operation diagram are as follows: According to the share gradual transfer entry, the ore discharge unit is switched to the ore discharge window occupancy state, and the concentrate release and collection in the collection section are carried out to generate the gold concentrate batch entry. Based on the gold concentrate batch entries and share gradual transfer entries, the share distribution entries of the branch balanced ore supply set are written back and updated, and the ore discharge execution entries are merged to generate the ore discharge operation map update set.

[0015] As a preferred embodiment of the process layout method for Nelson gravity separation of the entire grinding feed stream described in this invention, the steps for generating the Nelson gravity separation operation record set are as follows: Read the updated set of the ore discharge operation chart, align the gold concentrate batch entries with the rotation ore discharge arrangement list according to the ore discharge window time window order, perform round splitting and time window truncation rearrangement, and generate the batch list archive preparation package; Perform duplicate write verification and conflict resolution on the batch list archive preparation package, and seal the updated content of the share distribution entries of the branch balanced ore flow set to generate the batch archive set; Extract the latest share distribution entries of the branch balanced ore supply set and the latest round order of the rotation ore arrangement list from the batch archive set, and perform rotation benchmark write-back to generate the rotation benchmark write-back set; Based on the rotation benchmark write-back set, align and splice the gold concentrate batch entries with the rotation ore sorting list, and attach the share distribution entries to generate the Nielsen reseparation operation record set.

[0016] The beneficial effects of this invention are as follows: by using the balanced cavity for slow-release distribution, multi-scale fluctuations of the slurry are decoupled and structured for output, providing a high-confidence steady-state benchmark for branch distribution, eliminating instantaneous shocks and improving the collection efficiency of multiple units; by using the share-gradual transfer and rotation of ore discharge, the smooth reconstruction of ore discharge load and precise coupling of collection status are achieved, avoiding flow step disturbances, preventing secondary loss of gold particles, and ensuring continuous, stable and efficient operation of the system.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Reference Figures 1-4 This is one embodiment of the present invention, which provides a process layout method for Nelson gravity separation of the entire grinding feed stream, comprising the following steps: S1: Collect the gold ore mill discharge slurry and merge it into the full material flow manifold. Perform equalization chamber slow release distribution, and at the same time allocate the branch share benchmark and the branch take-up order to generate the branch equalization feed flow set. S1.1: Collect the ore discharge slurry from the gold ore mill, and record the slurry volumetric flow rate, slurry density, and slurry solids concentration to generate a full discharge ore collection entry; Furthermore, the timestamps and location identifiers of the gold ore mill discharge slurry are registered and the collection cycle is kept consistent. Based on the collection cycle, the arrival order of the slurry volumetric flow rate sampling values ​​is normalized and short-term missing measurements are interpolated. The range consistency of the slurry density sampling values ​​is checked and anomaly markers are registered for jump points. The sampling caliber of the slurry solids concentration sampling values ​​is standardized and neighborhood replacement is performed for outliers. The slurry volumetric flow rate, slurry density, and slurry solids concentration within the same collection cycle are aligned and encapsulated according to the collection timestamps and written into the collection location identifier to generate a full discharge collection entry.

[0026] S1.2: Merge all ore discharge collection entries into the total material flow manifold, perform inlet pulse merging, and generate the manifold inlet merged flow; Furthermore, the full discharge collection entries are arranged in the order of collection timestamps and written into the inlet alignment number of the full material flow manifold. Full discharge collection entries with abnormal intervals between adjacent collection timestamps are marked as pulsation candidate segments and merged into pulsation segment groups according to the inlet alignment number. Inlet pulsation merging is performed on each pulsation segment group. The slurry volume flow rate, slurry density and slurry solids concentration in the pulsation segment group are merged smoothly with a short window according to the inlet alignment number while keeping the boundary timestamp of the pulsation segment group unchanged. Non-pulsation segment groups are kept in their original order and connected directly to the merged pulsation segment groups according to the inlet alignment number to generate the merged flow manifold inlet flow.

[0027] S1.3: The merged flow from the manifold inlet is introduced into the equalization chamber of the full material flow manifold, and short-cycle slow-release slicing and long-cycle slow-release convergence are executed in sequence to generate the equalization chamber slow-release distribution item set; Furthermore, the merged flow from the manifold inlet is imported into the equalization chamber of the full-flow manifold according to the inlet alignment number and the entry timestamp is recorded. Short-cycle slow-release slicing is performed on the merged flow from the manifold inlet in the equalization chamber of the full-flow manifold. The continuously arriving segments are divided into short-cycle slow-release slices according to a fixed short-cycle length, and a slice number and short-cycle time window boundary are written for each short-cycle slow-release slice. The flow fluctuation within the slice is flattened and the slope of the slice boundary is limited to form a slow-release output segment. Long-cycle slow-release convergence is performed on multiple slow-release output segments within the same long-cycle time window. The slow-release output segments are aggregated into long-cycle slow-release convergence entries according to the long-cycle time window and written to the long-cycle time window boundary and convergence number. The short-cycle slow-release slicing results and the long-cycle slow-release convergence results are organized and packaged according to the inlet alignment number to generate the equalization chamber slow-release distribution entry set.

[0028] like Figure 2As shown, comparing the volumetric flow rate of the combined flow at the inlet of the full-flow manifold with the output of the slow-release distribution from the equalization chamber, the inlet curve exhibits a composite fluctuation of high-frequency pulsation superimposed with low-frequency drift. In contrast, the output of the slow-release distribution from the equalization chamber smooths out instantaneous peaks and valleys through short-cycle slow-release slicing and reconstructs the slow-changing trend into a steady state through long-cycle slow-release convergence, resulting in significantly reduced output fluctuation amplitude and controlled slope changes. The magnified window corresponding to the red dashed box in the figure is used to display the detailed differences between the two curves within the same time period: the inlet peaks and valleys are sharper, and the spacing between adjacent peaks is more irregular, while the slow-release output peaks are smoother and the peak-valley difference is smaller. This forms a high-confidence steady-state benchmark that can be used for branch share benchmark freezing and phase acquisition programming, thereby supporting the structured output and shock-resistant operation of subsequent branch equalization feeding.

[0029] S1.4: Based on the equalization cavity slow-release distribution entry set, perform branch share base freezing and branch access phase arrangement to obtain the branch distribution arrangement entry set; Furthermore, the equalization cavity slow-release distribution entry set is expanded into long-cycle slow-release convergence entries according to the aggregation sequence number of the long-cycle time window. The available flow scale of the slow-release output segment within each long-cycle time window is extracted and converted into the target utilization share of each branch, forming a branch share benchmark and writing it into the effective time window. The consistency check is performed on the fluctuation amplitude of the branch share benchmark within multiple consecutive long-cycle time windows. When the fluctuation limit condition is met, the freezing sequence number is registered to complete the freezing of the branch share benchmark. Based on the branch share benchmark corresponding to the freezing sequence number, each long-cycle time window is divided into phase slots and a phase rotation table is generated. The utilization phase start point and phase duration are assigned to each branch according to the phase rotation table, and the branch utilization phase arrangement and branch utilization order are output. The freezing sequence number, effective time window, branch share benchmark, and branch utilization phase arrangement are encapsulated into a branch distribution arrangement entry set.

[0030] It should be noted that the fluctuation limit condition refers to comparing the change range of the same branch share benchmark within multiple consecutive long-term time windows, and the change range always remains within the pre-agreed allowable fluctuation range (for example, the difference of the branch share benchmark between adjacent long-term time windows does not exceed 5%).

[0031] S1.5: Expand the current share of the branch based on the branch distribution arrangement entry set, obtain the share distribution entry, and perform share closure verification and gap backfilling registration to generate the branch balanced ore feed flow set; Furthermore, based on the branch distribution arrangement item set, the usage period of each branch is expanded according to the effective time window and phase rotation table. The branch share benchmark is mapped to the phase slot, and the current usage share of the branch is calculated within the phase slot. The current usage share of the branch is registered as a share distribution item according to the branch usage order, and the corresponding phase start point and phase duration are written. For all share distribution items within the same effective time window, a share closure check is performed, the difference between the total value of the share distribution items and the target closure value is calculated, and the gap direction and gap size are registered. For share distribution items whose gap size is within the backfilling range, gap backfilling registration is performed. The gap is allocated to the share distribution items with longer phase durations according to the phase rotation table, and the backfilling sequence number and backfilled share value are written. The backfilled share distribution items and the corresponding branch usage order are encapsulated into a branch balanced feed flow set.

[0032] It should be noted that the example of the backfill range is that the ratio of the gap size to the target closure value is in the range of 0.2% to 2.0%. The backfill range is obtained by taking the absolute value of the difference between the total value of the share distribution items and the target closure value, and then normalizing it according to the target closure value to obtain the ratio. The ratio is then compared with the lower limit and the upper limit to determine whether it falls within the backfill range.

[0033] The formula for calculating the total value of share distribution items is: ; The formula for calculating the target closure value is: ; in, Indicates the effective time window Total value of internal share distribution items Indicates the effective time window The internal parameters utilize the arranged set of phase slots. Indicates the phase slot index, Indicates within the effective time window Phase slot index The corresponding branch index, Indicates the effective time window inner branch road Branch share benchmark, Indicates the effective time window Inner phase slot The phase duration, This indicates that the share is far from the walking distance. Indicates the lower limit of the share. Indicates the upper limit of the share. This represents the upper and lower limit clipping operator, which restricts the input value to a range. Inside, This represents the rounding operator, used to quantize the result to the nearest discrete grid point. This represents the total weights used for normalization. This indicates the backfill sequence number in the gap backfill registration. Indicates the effective time window Internal target closure value.

[0034] It should be noted that the lower limit of the share is calculated based on the minimum stable ore supply capacity of the branch corresponding to the branch balanced ore supply flow set and the minimum feed volume required to maintain continuous capture position of the centrifugal bed of the parallel Nelson gravity separator unit, and serves as the lower bound for the share cut.

[0035] The upper limit of the share is calculated based on the maximum distributable flow rate of a single branch of the full material flow manifold and the maximum allowable throughput of the parallel Nelson reselection unit inlet, combined with the backfill margin of the equalization chamber slow release distribution, and serves as the upper limit of the share cut.

[0036] S2: The branch balanced feed flow is collected and sent to the parallel Nelson gravity separator unit for centrifugal bed capture and solidification. The free gold, coarse gold and high-density heavy sand in the gold mill discharge slurry are solidified into a stable capture section, generating a parallel online operation diagram. S2.1: Establish a corresponding access relationship between the branch balanced feed flow set and the parallel Nelson gravity separation unit, and arrange them into a parallel access list based on the branch share benchmark and the branch access order; Furthermore, the branch balanced feed flow set is expanded according to the branch access order, and a branch number and effective time window are written for each branch. For parallel Nielsen re-selection units, the set is expanded according to the equipment identifier, and the unit number and accessible access diameter are written. A one-to-one matching verification is performed based on the unit number and branch number, and the corresponding access relationship is registered. For unmatched branches, a candidate mark is applied and the candidate priority is registered. For matched branches, the branch share benchmark and branch access order in the branch balanced feed flow set are written into the corresponding access relationship to form an access entry. The access entries are sorted according to the branch access order and grouped and encapsulated according to the unit number to generate a parallel access list.

[0037] S2.2: According to the parallel access list, the branch balanced feed flow is sent to the parallel Nelson gravity separation unit and the centrifugal bed is loaded. Free gold, coarse gold and high-density heavy sand are written into the continuous capture position status of the centrifugal bed, the capture ready lock is executed, and the capture ready list is generated. Furthermore, the parallel access list is executed item by item according to the branch access order. The branch corresponding to the access item is balanced to the ore flow collection and imported into the corresponding entry of the parallel Nelson gravity separation unit within the effective time window and written into the access timestamp. Centrifugal bed loading is performed for each parallel Nelson gravity separation unit. The branch share benchmark corresponding to the access item is converted into the centrifugal bed loading rhythm and the loading start and end time windows are recorded. During the centrifugal bed loading, a capture occupancy registration is established for free gold, coarse gold and high-density heavy sand in the gold ore mill discharge slurry. The capture occupancy registration is written into the continuous capture occupancy status of the centrifugal bed and a continuous ore supply time window boundary is attached. The capture ready lock is executed for the continuous capture occupancy status of the centrifugal bed. The lock start timestamp, lock duration window and corresponding access item are written into the lock item and a capture ready item in the unit is generated. The capture ready items of each parallel Nelson gravity separation unit are summarized and packaged according to the branch access order to generate a capture ready list.

[0038] S2.3: Based on the capture readiness list and taking the continuous ore supply time window as the boundary, define and register the stable capture section of the continuous capture occupancy status of the centrifugal bed layer, and summarize it into a stable capture section list. Furthermore, the capture ready list is expanded item by item according to the equipment identifier of the parallel Nelson gravity separation unit, and the locking start time stamp, locking duration window, and continuous ore supply time window boundary are extracted. The continuous ore supply time window boundary is mapped to the segment boundary candidate boundary and written into the segment boundary number. The continuous capture occupancy status of the centrifuge bed is divided into occupancy segments within the segment according to the segment boundary number, and the start and end timestamps of the occupancy segments within the segment are retained. The continuity check of the occupancy segments within the segment is performed to verify the coverage duration of the occupancy segments within the segment and the continuity of the occupancy registration. The interrupted segments are marked for removal. The occupancy segments within the segment that pass the continuity check are registered as stable capture segments and the start and end boundaries of the stable capture segments and the corresponding equipment identifier are written into them. The stable capture segments of each parallel Nelson gravity separation unit are sorted and summarized according to the equipment identifier, and the segment boundary number and the start and end boundaries of the stable capture segments are encapsulated to generate a stable capture segment list.

[0039] It should be noted that the continuous ore supply time window takes the lock start time stamp corresponding to the equipment identifier of the same parallel Nelson resembling unit in the capture ready list as the window start time and the lock duration window end time as the window end time. The maximum continuous coverage interval obtained by deducting the interrupted segments with the removal mark registered in the continuity check from the coverage interval is used as the boundary of the continuous ore supply time window.

[0040] S2.4: Based on the stable capture segment list, bind the corresponding access relationship, branch share benchmark and branch access order of the parallel access list to the start and end boundaries of the stable capture segment to generate a parallel online operation diagram; Furthermore, the stable capture segment list is expanded according to the equipment identifier and the start and end boundaries of the stable capture segment, and segment boundary numbers are written in. The parallel access list is expanded according to the equipment identifier and the corresponding access relationship, branch share benchmark, and branch access order are extracted. The stable capture segment list and the parallel access list are checked for consistency of equipment identifiers, and abnormal alignment marks are registered for inconsistent items. For consistent items, the corresponding access relationship, branch share benchmark, and branch access order are written into the start and end boundaries of the stable capture segment, and online ore supply items are generated. Multiple online ore supply items under the same equipment identifier are sorted according to the time order of the start and end boundaries of the stable capture segment and segment boundary continuity is checked. It is checked whether there is time overlap or time break between the start and end boundaries of adjacent stable capture segments and correction items are registered. The checked online ore supply items are summarized and packaged according to the equipment identifier and a segment boundary number sequence is attached to generate a parallel online operation diagram.

[0041] S3: Based on the parallel online operation diagram, perform anti-fluctuation share steady-state maintenance within the full material flow manifold, mark the ore-discharging units to be dispatched in the current round, and generate a rotation ore-discharging schedule list; S3.1: Read the parallel online operation diagram and extract the access relationship, branch share benchmark and branch access order, merge them into the share reference table, and perform branch access phase playback locking to generate manifold maintenance input packet; Furthermore, the parallel online operation diagram unfolds the online ore supply entries in chronological order, extracts the corresponding access relationship, branch share benchmark, and branch access order for each online ore supply entry, and performs deduplication and reconciliation of duplicate entries according to the branch access order, and verifies the coverage of the time window, and organizes them into a share reference table; based on the share reference table, the branch access order is mapped to the phase rotation index, the phase start point and phase duration are replayed according to the start and end boundaries of the stable capture segment, and the lock start time timestamp and lock duration window are written, the consistency of the phase rotation index is checked and the branch access phase replay lock sequence number is registered, and the share reference table and the branch access phase replay lock sequence number are merged and encapsulated to generate the manifold maintenance input package.

[0042] S3.2: Import the manifold maintenance input package into the full material flow manifold, sequentially take the long-cycle output segments from the equalization chamber slow release distribution item set, and perform share correction in conjunction with the share reference caliber table to generate an anti-fluctuation share steady-state maintenance package. Furthermore, the manifold maintenance input package is written into the effective time window of the full material flow manifold and the share reference caliber table is registered as the positive caliber. The long-cycle output segments are sequentially retrieved according to the long-cycle time window aggregation sequence number of the equalization chamber slow release distribution item set, and a retrieval sequence number is written for each long-cycle output segment. The available flow scale of the long-cycle output segment is extracted for each retrieval sequence number, and the branch target retrieval share is expanded according to the share reference caliber table. The share distribution items of the branch equalization feed flow set are used as the reference caliber to generate branch deviation items. The share positive caliber is performed on the branch deviation items. The branch deviation items with the same deviation direction are registered as positive caliber candidates and the positive caliber priority is assigned according to the branch retrieval phase playback lock sequence number. The positive caliber amount is allocated and registered for the positive caliber candidates and written into the positive caliber share value. The retrieval sequence number, positive caliber, branch deviation item and positive caliber share value are encapsulated into an anti-fluctuation share steady-state maintenance package.

[0043] It should be noted that the anti-fluctuation share steady-state maintenance package refers to the set of records obtained after aligning the available flow scale of the long-cycle output segment with the share reference caliber table according to the retrieval sequence number and completing the share correction. The set contains the correction caliber, branch deviation entries and the corrected share value, which are used to maintain the steady-state consistency of the branch retrieval share within the effective time window on the full material flow manifold side.

[0044] S3.3: Based on the anti-fluctuation share steady-state maintenance package, summarize the continuous ore supply time window of the stable collection segment, mark the ore-to-discharge unit in the current round, and extract the online set of parallel Nelson gravity separation units to generate a round pointing package; Furthermore, based on the stable maintenance package of the anti-fluctuation share, the positive value of the share after being expanded according to the retrieval sequence number and the effective time window, the start and end boundaries of the stable capture segment in the parallel online operation diagram are projected according to the effective time window, and time window splicing and overlap removal are performed to summarize the continuous ore supply time window of the stable capture segment and write it into the round time window sequence number; according to the round time window sequence number, the equipment identifiers in the parallel online operation diagram are registered for round occupancy, and a ore sorting sequence is generated according to the coverage duration of the stable capture segment corresponding to the equipment identifier. The equipment identifier with the highest sorting position in the ore sorting sequence is written into the ore to be discharged in the current round. The generator set field is used to write the ore to be discharged and the round time window number into the corresponding equipment identifier entry in the parallel online operation diagram. At the same time, the remaining equipment identifier entries are written with the non-ore to be discharged marker and the corresponding sorting position to complete the clear marking of the generator set to be discharged in the current round. The equipment identifier survival check is performed on the parallel online operation diagram and the online valid time window is registered. The set of equipment identifiers covering the round time window number of the online valid time window is extracted to form the online set of parallel Nelson re-separation generator sets. The continuous ore supply time window, the generator set to be discharged in the current round and the online set of parallel Nelson re-separation generator sets are encapsulated into a round pointer package.

[0045] S3.4: Merge the round pointing packet and the manifold maintenance input packet according to the branch access order, and write the branch share gradual transfer starting caliber corresponding to the ore unit to be dispatched to generate the rotation dispatching list. Furthermore, the round-direction package is expanded into a continuous ore supply time window, the online set of the ore-to-be-distributed units in the current round and the parallel Nelson gravity separation units, and the manifold maintenance input package is expanded into a share reference caliber table and a branch access phase playback lock sequence number. The continuous ore supply time window is projected one by one according to the branch access order in the share reference caliber table to generate branch time window entries and write the branch access phase playback lock sequence number. According to the location of the ore-to-be-distributed units in the current round, the corresponding access relationship is located, and the corrected share value of the corresponding branch of the ore-to-be-distributed units is extracted from the share reference caliber table and registered as the branch share gradual transfer starting caliber. The online set of parallel Nelson gravity separation units is generated according to the branch access order and the acceptance order entry is written with the acceptance start time stamp. The branch time window entries, the branch share gradual transfer starting caliber, and the acceptance order entries are encapsulated and organized according to the branch access order to generate a rotation ore distribution scheduling list.

The online collection of parallel Nelson gravity separation units is expanded according to the acceptance order and written with the acceptance start time stamp. On the full material flow manifold side, the share transfer source identifier is registered for the branch corresponding to the mining units to be scheduled in the current round, and the share transfer destination identifier is registered for the branch corresponding to the acceptance order entry. A one-to-one pairing of the share transfer source identifier and the share transfer destination identifier is established according to the branch time window entries and written with the pairing sequence number. For each pairing sequence number, the transfer time window boundary, the transfer rhythm segment point, and the rhythm level are registered. The starting caliber of the branch share gradual transfer is written with the pairing sequence number and the target closure value is registered. The pairing sequence number, share transfer source identifier, share transfer destination identifier, transfer time window boundary, and transfer rhythm segment point are encapsulated into a share gradual transfer execution list.

[0047] S4.2: Perform a share-decreasing and increasing redistribution on the share-gradual transfer execution list, move the share of the corresponding branch of the ore-dispatch unit to the online set of parallel Nelson gravity separation units, and generate share-gradual transfer entries; Furthermore, the share gradual transfer execution list is expanded item by item according to the pairing sequence number. The share transfer source identifier, share transfer destination identifier, transfer time window boundary, and transfer rhythm segmentation point are extracted. The transfer time window boundary is divided into multiple redistribution segments according to the transfer rhythm segmentation point and written into the segment sequence number. The share decreasing and increasing redistribution step size of each redistribution segment is obtained and the step size sequence is recorded. The share of the corresponding branch of the mining unit to be dispatched is gradually deducted according to the step size sequence and the deducted share is gradually added to the branch corresponding to the share transfer destination identifier in the online set of parallel Nelson heavy separation units. At the end of the redistribution segment, the target closure value of the share transfer source identifier and the share transfer destination identifier is checked and the closure difference is recorded. The pairing sequence number, redistribution segment, step size sequence, deducted share, and closure difference are encapsulated into a share gradual transfer item.

[0048] like Figure 3 As shown, with the relative discharge start time as the horizontal axis, the actual feed flow response of the discharge unit under two share switching strategies within the discharge window is compared: G1 represents a step share switching, and G2 represents a gradual share transfer. Upon entering the discharge window, the G1 curve shows a steeper flow drop and a stronger nonlinear rebound in the recovery segment, exhibiting typical step disturbances and transition segment impacts. The G2 curve, on the other hand, distributes the flow change across multiple consecutive moments through a share-decreasing and increasing redistribution, making the feed flow decrease and recovery process smoother, the slope more limited, and the fluctuation return more stable. This difference in response directly corresponds to the execution effect of "establishing share transfer correlation and generating gradual share transfer entries on the full material flow manifold side," and can be used to verify the technical role of gradual transfer in avoiding flow step disturbances, mitigating the impact of discharge switching on the capture state, and ensuring continuous and stable parallel online operation.

[0049] Among them, G1 (Step Share Switching): At the moment of switching the ore discharge window, the share of the branch corresponding to the ore discharge unit is changed from the steady-state share to the target share in one go, and the released share is allocated to the receiving branch in one go and then the total share is closed and checked; the share instruction is a single sudden change, and the disturbance is concentrated at the time boundary, which is usually manifested as a steeper drop in flow, a stronger recovery rebound, and a more obvious transition shock; when setting the group, the parallel online operation diagram, the ore discharge window boundary, the initial steady-state share and the total constraint are kept consistent, and the strategy is only set to "single point write back the new share distribution entry", without generating share gradual transfer entries.

[0050] G2 (Gradual Share Transfer): Within the same ore discharge window, share transfer associations are first established, and the same share change is broken down into multiple consecutive decreasing-increasing redistributions. A sequence of gradual share transfer entries is generated according to the segment points, executed segment by segment, and closed and checked segment by segment. The share instructions are continuously and gradually changed, the flow change is distributed and the slope is limited, the decline and rise are smoother, and the fluctuation return is more stable. When setting the group, the operation chart, window boundary, initial share and total constraints are kept consistent. Only the strategy is set to "multi-segment small step update and output of the sequence of gradual share transfer entries".

[0051] S4.3: Based on the share gradual transfer entry, switch the ore discharge unit to the ore discharge window occupancy state, and carry out the release and collection of concentrate in the collection section to generate the gold concentrate batch entry. Furthermore, the share gradual transfer entries are expanded according to the pairing sequence number, the timestamp of the end of the redistribution segment that meets the target closure value is located, the time window boundary of the discharge window corresponding to the ore discharge unit is registered and the ore discharge window occupancy status mark is written; within the time window of the discharge window, the start and end boundaries of the stable collection section of the ore discharge unit are divided into collection section concentrate release sections, the collection section concentrate release entries are collected according to the concentrate release section sequence number and written into the batch number and collection time window, and packaged into gold concentrate batch entries.

[0052] S4.4: Based on the gold concentrate batch entries and share gradual transfer entries, write back and update the share distribution entries of the branch balanced ore supply set, and merge the ore discharge execution entries to generate the ore discharge operation map update set; Furthermore, the gold concentrate batch entries are expanded by batch number and the collection time window, the ore discharge window occupancy status marker, and the concentrate release entries in the collection section are extracted. The share gradual transfer entries are expanded by pairing sequence number and the redistribution segment end timestamp, share transfer destination identifier, and final usage share are extracted. The redistribution segment end timestamps are aligned by the collection time window, and the final usage share is written into the share distribution entries of the branch balanced ore flow set and the write-back version number and effective time window are registered. The concentrate release entries in the collection section, the step size sequence deduction entries, and the write-back version number are encapsulated into ore discharge execution entries. The ore discharge execution entries and share distribution entries are summarized by batch number and branch usage order to generate the ore discharge operation map update set.

[0053] like Figure 4As shown, the total secondary losses of multiple parallel units during the ore discharge rotation cycle are statistically analyzed, and the results of G1 (equilibrium chamber only, step switching) and G2 (complete scheme, gradual share transfer) are compared. The bar chart shows that the total secondary losses of each unit are generally lower under G2 conditions than under G1 conditions, and the difference maintains a consistent trend across different units. This indicates that gradual transfer achieves smooth reconstruction of ore discharge load and closer coupling of capture state during cross-unit rotation ore discharge: by making the share change continuous, the transient disturbances and material flow redistribution impact introduced by ore discharge switching are reduced, and the probability of gold particle re-entrainment and secondary loss during switching is reduced. This figure corresponds to the process result of "generating gold concentrate batch entries and writing back to update share distribution entries to form an updated set of ore discharge operation charts," and can serve as quantitative evidence to verify "preventing secondary gold particle loss and ensuring continuous, stable, and efficient operation."

[0054] Among them, G1 (equilibrium chamber only, step share switching): During the parallel unit rotation and ore discharge cycle, only the equilibrium chamber is used to slowly release the flow to suppress the inlet fluctuation. However, when the rotation reaches the ore discharge window, the share of the branch corresponding to the unit to be discharged is changed to the ore discharge target share in one go, and the released share is transferred to the receiving unit in one go, forming a "single-point switching" share update method. Under this setting, the disturbance is concentrated and injected into the switching boundary, the material flow redistribution is more abrupt, the total secondary loss is often higher, and the difference between units is amplified synchronously with the rotation rhythm. When setting the group, the number of units, the rotation and ore discharge arrangement list, the ore discharge window boundary, the total ore supply scale and the total share closure constraint are kept consistent. Only the "share update strategy" is fixed as step switching and no share gradual transfer item sequence is generated.

[0055] G2 (Complete Scheme, Gradual Share Transfer): Under the same rotation and discharge cycle and the same discharge window boundary, in addition to the equalization chamber slow-release distribution, a share transfer association is established on the full material flow manifold side. The share change of each rotation switch is broken down into multiple consecutive small-step decreasing-increasing redistribution, and a share gradual transfer entry sequence is generated and executed according to the segment points. At the same time, the share closure verification and share distribution entry back-write are completed segment by segment to form the discharge operation map update set. This setting distributes the switching disturbance and limits the slope, making the discharge load smoother and the capture state coupling tighter during cross-unit rotation. The total secondary loss shows a consistent decreasing trend across all units. The group setting also keeps the other conditions unchanged, only changing the "share update strategy" to gradual transfer and enabling the corresponding entry sequence and back-write link.

[0056] S5: Perform batch archiving and rotation baseline write-back on the updated set of ore discharge operation diagrams, merge the gold concentrate batch entries with the rotation ore discharge arrangement list, and generate the Nielsen reseparation operation record set; S5.1: Read the updated set of the ore sorting operation chart, align the gold concentrate batch entries with the rotation ore sorting list according to the ore sorting window time window order, perform round splitting and time window truncation rearrangement, and generate the batch list archive preparation package; Furthermore, the ore discharge operation map update set is expanded according to the ore discharge window time window sequence and the batch number, ore discharge window occupancy status marker, and ore discharge execution item are extracted. At the same time, the items in the rotation ore discharge arrangement list that are at the same time scale as the ore discharge window time window are extracted and written into the alignment index. For each ore discharge window time window, the round split is performed based on the alignment index. The rotation ore discharge arrangement list items that cross the boundary of the ore discharge window time window are split into window fragments and the round sub-sequence number is registered. The window fragments that do not completely fall into the ore discharge window time window are truncated and the truncation reason marker is written. The gold concentrate batch item corresponding to the batch number and the window fragment are rearranged according to the round sub-sequence number and the reorder number is written. A batch-level association relationship is established between the reorder number and the ore discharge execution item, and it is packaged into a batch list archive preparation package.

[0057] S5.2: Perform duplicate write verification and conflict resolution on the batch list archive preparation package, and seal the updated content of the share distribution entries of the branch balanced ore flow set to generate the batch archive set; Furthermore, the batch list archiving preparation package is expanded by batch number and reordering number, extracting gold concentrate batch entries, fragments within the rotation ore scheduling list window, and ore scheduling execution entries. A write fingerprint is generated and compared with the archived write fingerprint table item by item to perform duplicate write verification. Duplicate entries are registered for duplicate types, and timestamps are retained to update the newer entries. For inconsistent update content of share distribution entries for the same batch number, conflict segmentation is performed on the update content according to the ore scheduling window time window boundary. Conflict segments are resolved according to reordering number priority and written to the conflict resolution record. The updated content of the resolved share distribution entries is archived according to the write-back version number, and an archive index is generated. The archive index, gold concentrate batch entries, fragments within the rotation ore scheduling list window, and ore scheduling execution entries are summarized into a batch archive set.

[0058] S5.3: Extract the latest share distribution entries of the latest branch balanced ore supply flow set and the latest round order of the rotation ore arrangement list from the batch archive set, and perform rotation benchmark write-back to generate the rotation benchmark write-back set; Furthermore, the batch archive is traversed and sorted by write-back version number and ore discharge window time window end time. The share distribution entry with the largest write-back version number is located and the share closure check pass mark is verified. The updated content of the branch balanced ore supply set share distribution entry in the share distribution entry is extracted and the write-back version number is recorded. The segments in the rotation ore discharge arrangement list window of the batch archive are traversed in parallel. The latest rotation order is sorted according to the continuity of the rotation sequence number and the priority of the reorder number and the rotation order verification result is generated. The updated content of the branch balanced ore supply set share distribution entry and the latest rotation order are written into the rotation benchmark write-back entry, the rotation benchmark write-back timestamp and write-back version number are written and a write-back lock mark is generated. The rotation benchmark write-back entries are summarized to form the rotation benchmark write-back set.

[0059] It should be noted that the pass mark for share closure verification is obtained by the share closure verification process performing consistency verification between the total value and the target closure value of the share distribution entries within the same effective time window. When the total value of the share distribution entries is consistent with the target closure value, the pass mark is written.

[0060] S5.4: Based on the rotation benchmark write-back set, align and splice the gold concentrate batch entries with the rotation ore arrangement list, and attach the share distribution entries to generate the Nielsen reseparation operation record set; Furthermore, the valid round order is locked according to the write-back version number and write-back timestamp in the rotation benchmark write-back set. The round order is mapped to the ore discharge window time window and the ore discharge unit to be discharged in the rotation ore discharge arrangement list. Gold concentrate batch entries are retrieved according to the start and end boundaries of the ore discharge window time window and the continuity of the batch number is verified. The gold concentrate batch entries and the rotation ore discharge arrangement list are aligned and spliced ​​with the ore discharge window time window and the ore discharge unit to be discharged to generate the operation record entry sequence. The share distribution entries are attached to the operation record entry sequence according to the write-back version number and written into the branch balanced ore flow set share distribution snapshot index. The operation record entry sequence is summarized to generate the Nielsen reselection operation record set.

[0061] In summary, this invention achieves graded decoupling and structured output of multi-scale fluctuations in slurry through balanced cavity slow-release distribution, providing a high-confidence steady-state benchmark for branch distribution, eliminating instantaneous shocks, and improving the collection efficiency of multiple units; and achieves smooth reconstruction of discharge load and precise coupling of collection state through gradual share transfer and rotation of discharge, avoiding flow step disturbances, preventing secondary loss of gold particles, and ensuring continuous, stable, and efficient operation of the system.
