[0002] In the modern ironmaking industry, with the increasing scarcity of iron ore resources and intensified marketization, the types and sources of ironmaking raw materials have become more diversified. In order to reduce ironmaking costs, enterprises have to choose more types of low-grade ores and alternative raw materials, which has led to a significant increase in the number of ore blending varieties.

[0003] Currently, the number of material storage compartments in ore blending yards is limited, while the variety of ore types is large, requiring a number of compartments far exceeding the yard's capacity, resulting in low material stacking efficiency. Summary of the Invention

[0006] The first aspect of this application provides a method for managing ore blending, applied to an ore blending yard, the ore blending yard including multiple material compartments, the method comprising: Before each type of ore is stockpiled at the ore blending yard, the compositional analysis results of each type of ore are obtained; Based on the analysis results of each component, the component similarity of each of the ores is screened, and the ores with a component similarity greater than or equal to a preset similarity are identified as a group of ores to be mixed. Each group of ores to be mixed includes at least two types of ores. For each group of ores to be mixed, the various ores are mixed according to the target mixing ratio of each ore to obtain a mixed ore; Each of the mixed ores is stacked into one of the hoppers.

[0007] Optionally, each of the ores comprises multiple elements, and at least some of the elements have different proportions in the ores. The screening of the compositional similarity of the various ores based on the analysis results of each component includes: Let i=1, obtain the similarity between elements with the i-th proportion in various ores. If the similarity is greater than or equal to a preset similarity threshold, the corresponding ore is selected as a candidate ore. The smaller the value of i, the greater the proportion of the element in the ore. Let i = i + 1, return to the step of obtaining the similarity between the elements with the i-th proportion in various ores, and if the similarity is greater than or equal to the preset similarity threshold, then the corresponding ores are selected as candidate ores.

[0011] Optionally, after obtaining the mixed ore, the method further includes: The mixed ore was subjected to component analysis; If the deviation between the component analysis result of the mixed ore and the preset mixed ore composition is greater than or equal to the preset deviation, the target mixing ratio of each ore is adjusted and the process returns to the step of controlling the mixing equipment to mix each ore, until the deviation between the component analysis result of the mixed ore and the preset mixed ore composition is less than the preset deviation.

[0012] Optionally, the step of stacking each of the mixed ores into one of the hoppers includes: Based on the layout parameters of the ore blending yard and the preset ore blending plan, a target storage compartment is determined for each of the mixed ores to be stacked. The mixed ore is piled into one of the target hoppers.

The earlier the taking order of the mixed ore is, the closer the cell of the target cell where the mixed ore is piled is to the mixing ore configuration site.

[0014] A second aspect of this application provides a mineral processing management device for use in a mineral processing yard, the mineral processing yard including multiple material compartments, the device comprising: An acquisition unit is used to acquire the compositional analysis results of each type of ore before each type of ore is stockpiled at the ore blending yard; The screening unit is used to screen the component similarity of various ores based on the component analysis results, and to take ores with a component similarity greater than or equal to a preset similarity as a group of ores to be mixed, wherein each group of ores to be mixed includes at least two kinds of ores.

[0026] In the ironmaking industry, with the increasing scarcity of iron ore resources and intensified marketization, the types and sources of ironmaking raw materials have become more diversified. To reduce ironmaking costs, companies have had to select a wider variety of low-grade ores and alternative raw materials, leading to a significant increase in the number of blending varieties. Currently, there are more than 30 blending varieties, each requiring at least two storage compartments and separate stacking. This not only results in low stockpiling efficiency but also increases the complexity of stockpiling and the frequency of switching, further reducing stockpiling efficiency.

[0027] Furthermore, due to the significant differences in ore composition from different sources, traditional ore blending management methods are ill-suited to effectively address this diversity and complexity. Blending typically relies on manual experience, lacking systematic component pre-detection and mixing techniques, making precise component control and variety optimization difficult. Frequent variety switching not only increases equipment wear and maintenance costs but also leads to production interruptions, impacting overall production efficiency. Simultaneously, the lack of real-time monitoring and dynamic adjustment mechanisms makes it difficult to guarantee the stability of the blended ore quality, which to some extent limits the flexibility and adaptability of ore blending.

[0028] While existing technologies offer methods for blending different mineral types, these methods typically fail to effectively address the issues of excessive quantity and poor quality stability. For instance, some methods rely solely on simple physical mixing to reduce the number of mineral types, resulting in inconsistent quality after blending.

[0029] In view of this, the present application provides a method for ore blending management. This method obtains the composition analysis results of each type of ore and performs a mixing process based on similarity to merge multiple ores with similar composition into a new mixed ore. This reduces the number of varieties that need to be managed in the yard and the number of material cells occupied, thereby improving the efficiency of ore blending management in the ore blending yard.

[0030] The ore blending management method of this application embodiment will be described below with reference to the accompanying drawings.

[0031] Figure 1 A flowchart of an embodiment of the ore blending management method of this application is shown.

[0032] The first aspect of this application provides a method for managing ore blending, applied to an ore blending yard, the ore blending yard including multiple material compartments, the method including but not limited to: Step S1. Before each type of ore is stockpiled at the ore blending yard, obtain the composition analysis results of each type of ore; It is understood that "before each type of ore is stockpiled at the blending yard" can mean: before each type of ore is transported to the blending yard using a means of transport, which can be a ship.

[0033] Before each type of ore enters the storage yard, its composition data is obtained. For example, before the ship arrives or at the beginning of the unloading operation, samples are tested using composition analysis equipment (such as X-ray fluorescence spectrometer) to obtain its chemical composition (content of TFe, SiO2, Al2O3, etc.) and physical properties (particle size distribution, bulk density, etc.). The test data is transmitted and stored in a pre-test database, providing basic data support for subsequent classification, combination, and mixing operations, and reducing the risk of mixing due to uncertain composition.

[0034] For example, a large steel company's raw material terminal received 26 transport ships from different mining areas, carrying 26 different types of iron ore: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, and Z. If these were directly stored separately in the ore blending yard's storage compartments, requiring separate stacking and retrieval, at least 52 storage compartments would be needed.

[0035] Before the 26 ships docked for unloading, representative ore samples were collected from the holds of each ship. The samples were then sent to compositional analysis equipment (such as an online XRF analyzer) for testing. The test results are as follows: Variety A: Total iron (TFe) 62.0%, silicon dioxide (SiO2) 3.5%, with relatively coarse particle size.

[0036] Variety B: Total iron (TFe) 58.5%, silicon dioxide (SiO2) 4.2%, medium particle size.

[0037] Variety C: Total iron (TFe) 63.2%, silicon dioxide (SiO2) 3.1%, finer particle size.

[0038] Similarly, the compositional analysis of 26 types of iron ore was completed, and the analysis data was stored in the pre-detection database.

[0039] Step S2. Based on the analysis results of each component, the component similarity of each ore is screened, and the ore with a component similarity greater than or equal to a preset similarity is taken as a group of ore to be mixed, wherein each group of ore to be mixed includes at least two kinds of ore; Understandably, cluster analysis is performed on multiple ore varieties based on similarity thresholds of chemical composition and physical properties. Varieties with similar compositions are grouped into the same ore group to be blended, thereby reducing the number of varieties managed independently. For example, ores with similar or complementary grades and impurity content within the same control range will be grouped together. This similarity-based screening enables dynamic optimization of ore resource allocation, providing a good foundation for subsequent blending.

[0040] In some embodiments, each of the ores comprises multiple elements, and at least some of the elements have different proportions in the ores. The screening of the compositional similarity of the various ores based on the analysis results of each component includes: Step S21. Let i=1, obtain the similarity between elements with the i-th proportion in various ores. If the similarity is greater than or equal to a preset similarity threshold, then the corresponding ores are selected as candidate ores. The smaller the value of i, the greater the proportion of the element in the ores. Understandably, all ores are sorted by element content from highest to lowest, with i=1 representing the element with the highest content (e.g., iron) being compared in each ore. The similarity of different ores in this element is calculated, and ores with a similarity reaching a preset threshold are considered for selection. This ensures that the blending process first meets the most important quality indicators, preventing the overall grade of the blended ore from becoming uncontrollable due to excessive fluctuations in the main element.

[0041] Step S22. Let i = i + 1, return to the step of obtaining the similarity between the elements with the i-th proportion in various ores. If the similarity is greater than or equal to the preset similarity threshold, then the corresponding ores are selected as candidate ores. After screening the primary elements, the next iteration begins. Let i = i + 1, and then screen for elements with lower abundance (such as silicon and aluminum). This progressive screening ensures that the selected ores are not only similar in their primary indicators but also highly consistent in their secondary components. This multi-level screening effectively avoids process problems such as coking and corrosion in mixed ores caused by neglecting secondary elements.

[0042] Step S23. Stop screening the compositional similarity of various ores until i=n, ​​where n represents the nth proportion of an element in the ore.

[0043] It is understandable that the nth percentage is not necessarily the percentage of the element with the smallest content in the ore, but may be the percentage of elements with a larger content, such as aluminum. That is, trace elements can be ignored when screening for composition similarity, thereby reducing the workload.

[0044] In some embodiments, before screening the compositional similarity of the various ores based on the respective compositional analysis results, the method further includes: Step S20. Obtain the chemical composition of the target element in each of the ores, classify the ores with the same chemical composition of the target element to obtain at least one ores series, wherein the proportion of the target element in the ores is greater than the proportion of other elements in the ores; The screening of the compositional similarity of various ores based on the analysis results of each of the aforementioned components includes: For each of the aforementioned ore series, the compositional similarity of various ores within the ore series is screened based on the compositional analysis results.

[0045] Understandably, the initial classification is based on the chemical composition of the most predominant target element in the ore (such as iron in iron ore and manganese in manganese ore), grouping ores with the same target element into the same ore series. For example, all ores with iron as the predominant element are classified into the iron ore series, and all ores with manganese as the predominant element are classified into the manganese ore series. This ensures that subsequent compositional similarity analysis is conducted within the same principal element system, improving classification efficiency.

[0046] Step S3. For each group of ores to be mixed, mix the various ores according to the target mixing ratio of each ore to obtain mixed ores; In some embodiments, before mixing the various ores according to a target mixing ratio for each of the ores, the method further includes: In a pre-set blending ore database, the target blending ratio for each type of ore is obtained, wherein the blending ore database includes the blending ratios of various ores corresponding to each type of blending ore.

[0047] Before performing the actual mixing operation, the precise proportions of each ore must first be determined. This embodiment uses a pre-defined blending ore database to record the mixing ratios of various ores corresponding to each blending ore. This database is a pre-validated knowledge base that stores standard formulations for various blending ores, detailing the types of raw materials and their mixing ratios for each type. When a specific blending ore needs to be produced, the corresponding proportioning parameters are retrieved from the database. This standardized database-based approach, compared to ad-hoc calculations or empirical estimations, ensures the scientific validity and repeatability of the proportions, avoiding human error, and also improves production response speed.

[0048] For example, if three types of ore (such as E, F, and G) have very small differences in grade, and according to the original ore blending plan, the resources of the three types of ore and their proportions in the blending are known, for example, the blending ratio is calculated as E:F:G = 4:2:4.

[0049] In some embodiments, mixing the various ores according to a target mixing ratio for each of the ores to obtain a mixed ore includes: Step S31. Prepare the ingredients according to the target mixing ratio for each of the ores; Step S32. The various ores after batching are transported to a mixing device, and the mixing device is controlled to mix each of the ores to obtain the mixed ore.

[0050] In some embodiments, after obtaining the mixed ore, the method further includes: The mixed ore was subjected to component analysis; If the deviation between the component analysis result of the mixed ore and the preset mixed ore composition is greater than or equal to the preset deviation, the target mixing ratio of each ore is adjusted and the process returns to the step of controlling the mixing equipment to mix each ore, until the deviation between the component analysis result of the mixed ore and the preset mixed ore composition is less than the preset deviation.

[0051] Understandably, after obtaining the precise target mixing ratio, various ores can be weighed and fed using precisely controlled batching equipment (such as quantitative feeders and electronic belt scales). Subsequently, specialized equipment such as stacker-reclaimers or blending stackers are used to uniformly mix the different ores together through flat cutting or layer-by-layer stacking processes. Throughout the mixing process, online detection methods are typically employed to monitor the quality fluctuations of the mixture in real time, ensuring that the final mixed ore has a uniform and stable chemical composition that meets the preset quality standards for blended ore.

[0052] For example, a high-precision weighing device (belt scale) is used to control the instantaneous flow rates of varieties E, F, and G in a 4:2:4 ratio. After the three ores are combined in the specified ratio, they enter a high-intensity mixer. The mixer blades vigorously agitate the ores at a set speed to eliminate particle size segregation. Online component analysis of the mixed ore reveals that fluctuations in the moisture content of variety F caused the TFe reading to momentarily drop to 60.5% (below the target value). This triggers a dynamic adjustment mechanism, instructing the weighing device to fine-tune the proportion of variety G (high grade) from 40% to 42%, while reducing the proportion of variety F accordingly. After 10 seconds of dynamic adjustment, the TFe reading recovers to 61.0%, ensuring the quality stability of the mixed ore.

[0053] Step S4. Stack each of the mixed ores into one of the hoppers.

[0054] In some embodiments, stacking each of the mixed ores into one of the hoppers includes: Step S41. Based on the layout parameters of the ore blending yard and the preset ore blending plan, determine a target storage cell for each of the mixed ores to be stacked; In some embodiments, the layout parameters include at least one of the following: number of material grids, size of material grids, location of material grids, and current usage status of material grids; the ore blending plan includes at least one of the following: the order of taking each of the mixed ores and the amount taken; and determining a target material grid for each of the mixed ores to be stacked based on the layout parameters of the ore blending yard and the preset ore blending plan includes: According to the taking order and the taking amount, the mixed ore is piled into a target cell that is in an idle state and has a suitable cell size. The earlier the taking order of the mixed ore is, the closer the cell of the target cell where the mixed ore is piled is to the mixing ore configuration site.

[0055] Step S42. The mixed ore is piled into one of the target hoppers.

[0056] Understandably, it's essential to comprehensively collect the layout parameters of the ore blending yard, including the total number of storage compartments, the specific dimensions of each compartment (length, width, height, and volume), the physical coordinates of each compartment within the yard, and the current real-time usage status of each compartment (idle, occupied, or reserved). These parameters collectively constitute the physical constraints of the storage space. A pre-set ore blending plan is introduced as a logical guide. The ore blending plan clarifies the order and quantity of ore to be extracted from each blend. The extraction order refers to the expected sequence of extractions and delivery to the next process (such as sintering or blast furnace), and the extraction quantity is the planned amount of ore to be extracted from that compartment.

[0057] Based on the above information, following the principle that the earlier the mixed ore is retrieved, the closer its target storage cell should be to the blending ore preparation area, can shorten transportation distances, reduce transfer costs and time, and improve overall operational efficiency. If the mixed ore is planned to be retrieved in the next shift, it should be prioritized for allocation to the cell closest to the blending hopper, while ore B, planned for retrieval several days later, can be placed in a relatively distant area. In addition to location priority, it is also necessary to ensure that the target storage cell is currently idle and that its size and volume can accommodate the total amount of mixed ore to be stored, thus coupling storage space with material flow requirements.

[0058] For example, if the fifth storage compartment in the ore blending yard is empty and is adjacent to the subsequent material handling line with the shortest transport distance, then the mixed ore currently awaiting transport can be placed in the fifth storage compartment. Thus, multiple ores that would normally require multiple compartments only require one, reducing compartment occupancy and freeing up yard capacity.

[0059] To gain a more comprehensive understanding of the mineral blending management method of this application embodiment, the complete implementation of the method will be illustrated below through specific application examples.

[0060] A large steel company's raw material terminal received three transport ships from different mining areas, each carrying one of three types of iron ore: type A, type B, and type C. Preliminary assessment indicated significant differences in the grade of these three ores. Directly storing them separately would require three separate storage compartments and necessitate frequent switching of ore types during subsequent loading, impacting blast furnace production efficiency. The specific implementation of the ore blending optimization system and method of this invention is as follows: 1. Component Pre-detection Stage Before the three ships docked for unloading, pre-sampling equipment was activated to collect representative ore samples from the holds of each ship. The samples were then sent to compositional analysis equipment (such as an online XRF analyzer) for testing. The test results are as follows: Variety A: Total iron (TFe) 62.0%, silicon dioxide (SiO2) 3.5%, with relatively coarse particle size.

[0061] Variety B: Total iron (TFe) 58.5%, silicon dioxide (SiO2) 4.2%, medium particle size.

[0062] Variety C: Total iron (TFe) 63.2%, silicon dioxide (SiO2) 3.1%, finer particle size.

[0063] The detection data is tagged and stored in the pre-detection database.

[0064] 2. Hybrid Planning Generation Phase Data from the pre-detection database was read and component similarity was screened. The screening process revealed that although the three ores had different grades, their components could be neutralized by mixing them in a specific ratio. Simultaneously, based on the blast furnace's target requirements for the feed material (target TFe of 61.0% and SiO2 of 3.6%), the optimal mix ratio was calculated to be 4:2:4 for variety A: variety B: variety C. This mixing scheme was defined as mixed ore M2, and its physicochemical properties after mixing were predicted to meet the blast furnace feed material standards.

[0065] 3. Mixing and processing stage Unloading operations have begun, and the three types of ore are being conveyed to the mixing line via belt conveyors: 1) Precise weighing: The high-precision weighing equipment (belt scale) controls the instantaneous flow of varieties A, B, and C in a 4:2:4 ratio.

[0066] 2) High-intensity mixing: After the three types of ore are combined in proportion, they enter a high-intensity mixer. The mixer blades vigorously agitate the ore at a set speed to eliminate particle size segregation.

[0067] 3) Online Monitoring and Adjustment: The mixed ore was analyzed using online component detection equipment. Monitoring revealed that fluctuations in the moisture content of variety B caused the TFe reading to momentarily drop to 60.5% (below the target value). This triggered a dynamic adjustment mechanism, instructing the weighing equipment to fine-tune the proportion of variety C (high grade) from 40% to 42%, while reducing the proportion of variety B accordingly. After 10 seconds of dynamic adjustment, the TFe reading recovered to 61.0%, ensuring the quality stability of the mixed ore M2.

[0068] 4. Yard stacking optimization stage The qualified mixed ore M2 was transported to the stockpile. A scan of the stockpile layout database revealed that storage cell #5 was empty and adjacent to the subsequent reclaiming line, minimizing transport distance. The automated stacker was then controlled to place all the mixed material into storage cell #5. As a result, the three types of ore, which originally required three cells, now only require one, reducing cell occupancy by 66% and freeing up stockpile capacity.

[0069] 5. Stack Optimization Phase After the mixed ore M2 has been stockpiled in the primary stockpile, a new stockpile construction plan is generated based on the stockpile volume of mixed ore M2. Stockpile construction equipment (such as a blending stacker) is used to extract material from the primary stockpile and spread it in layers in the secondary stockpile. In this way, the three single ore types, which originally had large fluctuations in composition and were complex to manage, are transformed into a mixed ore M2 finished material stockpile with highly uniform composition and convenient management, which meets the continuous and stable production requirements of the blast furnace.

[0070] Based on the above disclosures, this application's embodiments reduce the number of varieties requiring management in the yard by pre-detecting components and merging similar ore blends into new mixed varieties. This simplifies management processes, reduces operational difficulty and management costs, and improves the overall efficiency of the yard. Dynamically allocating stockpile locations based on the physical characteristics of the mixed varieties and the yard layout reduces the number of storage compartments, increases the yard's storage and transportation capacity, frees up more space for processing more raw materials, and enhances the yard's flexibility and adaptability. By reducing the number of varieties and optimizing material line switching and stockpile sequence, the switching frequency during stockpile construction is reduced, lowering equipment wear and maintenance costs. Utilizing component detection equipment to monitor changes in the composition of the mixed varieties and dynamically adjusting the system to optimize the mixing ratio ensures that the composition of the mixed varieties meets the ore blending requirements, improving product quality stability and consistency, and providing a reliable raw material guarantee for subsequent sintering processes.
