Description

Technical Field

[0001] This invention relates to an integrated device and method for high-energy-state conditioning and mineralization under pressure confinement, belonging to the field of mineral flotation technology. Background Technology

[0002] Mineral flotation is an important method for separating valuable minerals from gangue minerals by utilizing the differences in the physicochemical properties of mineral particle surfaces.

[0003] The essence of mineral flotation is to achieve selective enrichment of target minerals in a gas-liquid-solid three-phase system through interfacial interactions between particles and reagents, and between particles and bubbles. In existing industrial flotation systems, pulp conditioning is typically accomplished using mechanically agitated conditioning tanks, pipeline mixers, or static mixers. Mechanically agitated conditioning relies primarily on the macroscopic circulating flow generated by impeller rotation to mix reagents and pulp. With the increasing development of mineral resources, the feed ores are becoming leaner, finer, and more complex, with a significant increase in the proportion of fine-grained minerals. For smaller mineral particles, their motion is controlled by both hydrodynamic forces and interfacial forces, and the interactions between particles and reagents, and between particles and bubbles, exhibit significant multi-scale characteristics. Most existing conditioning equipment operates in open or semi-open flow environments with relatively simple flow field structures. The pulp interior mainly exhibits a single circulating flow or ordinary turbulent flow state, making it difficult to simultaneously achieve the synergistic enhancement of multiple processes such as particle transport, reagent diffusion, bubble breakage, and particle-bubble collisions. In addition, due to the limited energy utilization rate of the flow field, a large amount of input energy is only used to maintain macroscopic flow, and it is difficult to effectively transfer to the vicinity of the particle-agent-bubble interface, resulting in insufficient ability to regulate the microscale mineralization environment.

[0004] In summary, existing integrated high-energy conditioning and mineralization devices with pressure confinement suffer from problems such as a single flow field and low energy utilization efficiency, which in turn leads to low mineralization efficiency per unit energy.

[0018] The closer to the bottom of the mineralizer cylinder, the stronger the eddy current and vortex generator's turbulence design performance.

[0019] Furthermore, the chamber includes a third chamber located at the top of the mineralizer cylinder and a first chamber located at the bottom of the mineralizer cylinder; the stirring blade includes a third stirring impeller located in the third chamber and a first stirring impeller located in the first chamber; both the first stirring impeller and the third stirring impeller include vertical stirring blades radially distributed around the stirring shaft.

[0022] Furthermore, the stirring shaft is connected to the frequency converter via a coupling, and the frequency converter is connected to the frequency converter motor reducer; the coupling is connected to the mineralizer cylinder via a mounting base plate.

[0041] The technical solutions of this application / the embodiments thereof will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application / the embodiments thereof, and not all embodiments thereof. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application / the application thereof or its application or use.

[0042] Example 1:

[0043] This embodiment provides a pressure-confined high-energy-state conditioning and mineralization integrated device to solve the problem of low mineralization efficiency per unit energy caused by the single flow field and low energy utilization efficiency in the prior art.

[0044] refer to Figures 1 to 4 The pressure-confined high-energy-state conditioning and mineralization integrated device provided in this embodiment includes,

[0045] The mineralizer cylinder 5 has a lifting and guiding annular cavity 16 at its bottom. The inner cavity of the mineralizer cylinder 5 is also divided into multiple chambers 17 by multiple annular baffles 6. The annular baffles 6 have slits for contracting and cutting the fluid.

[0046] A stirring device is used to generate a circulating flow inside the mineralizer cylinder 5;

[0047] The ore inlet 12 is connected to the lifting and guiding annular cavity 16;

[0048] The ore outlet 14 is located at the top of the mineralizer cylinder 5.

[0049] In flotation, conditioning and mineralization are crucial steps determining the separation efficiency. Conditioning primarily facilitates the dispersion, transfer, and adsorption of reagents in the pulp, while mineralization enables the collision, adhesion, and stable transport of hydrophobic particles and air bubbles. Conditioning effectiveness directly impacts mineral surface properties, while mineralization efficiency determines the final flotation recovery rate and separation selectivity. Existing research indicates that the collision probability between particles and air bubbles, induction time, liquid film discharge rate, and adhesion stability are all closely related to the local flow field structure. When the flow field is too gentle, the contact opportunities between particles and air bubbles are limited; conversely, excessively high local turbulence can easily lead to the desorption and destruction of existing mineralization. Therefore, relying solely on a single flow regime is insufficient to simultaneously address the dual requirements of particle transport and mineralization stability. Current conditioning equipment generally lacks the ability to construct differentiated flow field environments for different mineralization stages, making it difficult to create a synergistic environment conducive to particle activation, reagent adsorption, air bubble miniaturization, and efficient particle-air bubble mineralization.

[0050] In this embodiment, the pressurized confined high-energy-state conditioning and mineralization integrated device provides the following: During use, the gaseous slurry enters the lifting and guiding annular cavity 16 from the inlet 12. Due to inertia, the gaseous slurry spontaneously flows within the lifting and guiding annular cavity 16 and is lifted upwards by the cavity to form a lifting flow. The upwardly guided gaseous slurry passes through each annular baffle 6 sequentially. Because the gaseous slurry circulates within the mineralizer cylinder 5, it spontaneously undergoes stratification under the influence of inertia, centrifugal force, and centripetal force. Bubbles and mineral particles with good adhesion to the bubbles move closer to the center of rotation and gradually pass upwards through the central hole of the annular baffle 6 under the influence of the lifting flow and buoyancy. Meanwhile, mineral particles with poor adhesion to the bubbles move closer to the inner wall of the mineralizer cylinder 5 and collide with the annular baffle 6 under the influence of the lifting flow. During the collision with the annular baffle 6, a portion of the gaseous slurry... The gaseous slurry is bounced back by the annular baffle 6. The bounced flow has an angle difference with the original flow direction, which in turn causes turbulence in each chamber 17, solving the problem of a single flow field and promoting the combination and adhesion of mineral particles and bubbles. Another part of the gaseous slurry is cut and compressed by the slits on the annular baffle 6, which generates local jets, wake vortices and small-scale eddies, promoting the adhesion between mineral particles and bubbles. The mineral particles with better adhesion to bubbles tend to gather towards the center and upward, and then directly pass through the central hole of one or more annular baffles 6, realizing the screening and separation of slurries with different mineralization degrees. At the same time, the initial velocity and inertia of the gaseous slurry when entering the mineralizer cylinder 5, as well as the lifting and guiding effect of the annular cavity 16, combined with the stirring of the stirring device, drive the flow of liquid and the adhesion between mineral particles and bubbles, thereby improving the mineralization efficiency per unit energy.

[0051] In summary, the pressurized confined high-energy-state conditioning and mineralization integrated device provided in this embodiment utilizes the initial velocity and inertia of the gaseous slurry to achieve efficient energy utilization by lifting and guiding the flow. On this basis, the complexity of the slurry flow is increased by the rebound of the annular baffle 6 and the disturbance effect of its gaps, thereby promoting the adhesion between bubbles and mineral particles. The mineral particles with different degrees of mineralization are classified by gravity and the action of the annular baffle 6, so as to extract well-mineralized slurry with high mineralization efficiency per unit energy.

[0052] Furthermore, it is worth noting that the internal flow field of traditional equipment is limited by the equipment size. Fluid in large-scale spaces easily forms short-circuit flows, dead zones, and energy dissipation regions, resulting in uneven distribution of slurry residence time and significant differences in the hydrodynamic conditions experienced by particles, thus affecting the consistency of conditioning and mineralization processes. Particularly in the flotation of fine-grained minerals, due to the small particle mass and insufficient inertia, their trajectories are more easily affected by local flow field fluctuations, further exacerbating the instability of the mineralization process. The pressure-confined high-energy-state conditioning and mineralization integrated device provided in this embodiment constructs a flow environment with pressure-constrained characteristics within a confined space. Through the synergistic coupling of multiple flow regimes, it achieves efficient interaction between particles, reagents, and bubbles, forming a multi-scale flow field system that combines enhanced conditioning and promoted mineralization, thereby improving the surface modification efficiency of mineral particles and the particle-bubble mineralization efficiency.

[0053] Example 2:

[0054] This embodiment provides a pressure-confined high-energy-state conditioning and mineralization integrated device. This embodiment is an optimization based on Embodiment 1 to improve the technical effect and refine the technical solution. For details not described in this embodiment, please refer to Embodiment 1.

[0055] In one embodiment, the cavity of the lifting and guiding annular cavity 16 is truncated cone-shaped, and the large base of the lifting and guiding annular cavity 16 is located on its small base.

[0056] The direction of the ore inlet 12 is tangent to the inner wall of the truncated cone of the lifting and guiding annular cavity 16, and the height of the connection point between the ore inlet 12 and the lifting and guiding annular cavity 16 does not exceed the height threshold.

[0057] In use, the gaseous slurry flows smoothly from the inlet 12 into the inner wall of the truncated cone-shaped cavity 16. Within the same height, the horizontal cross-section of the truncated cone is circular. As the gaseous slurry flows along it, influenced by the initial velocity and inertia, it tends to flow away from the smaller base of the truncated cone and towards the larger base, thus macroscopically exhibiting an upward lifting flow. To ensure the effectiveness of the lifting flow, the height of the connection point between the inlet 12 and the lifting annular cavity 16 does not exceed a height threshold.

[0058] In one embodiment, the stirring device includes a stirring shaft 9 located at the center of the inner cavity of the mineralizer cylinder 5. Different chambers 17 have different heights and positions, resulting in different degrees of mineralization in the slurry. Therefore, the stirring shaft 9 is equipped with stirring blades corresponding to different chambers 17. Mineralization is promoted in the chambers 17 with lower heights, and the stratification of slurries with different degrees of mineralization is promoted in the chambers 17 with higher heights, thus avoiding the desorption and destruction of the mineralized body. When the stirring shaft 9 rotates, the stirring blades generate a circulating flow in the inner cavity of the mineralizer cylinder 5, which, in turn, cooperates with the lifting flow generated in the lifting and guiding annular cavity 16 to promote the mixing of gas and particles in the slurry.

[0059] In one embodiment, the top cover of the mineralizer cylinder 5 is spherical, with the center being further away from the bottom. The air outlet 13 and the ore outlet 14, which communicate with the inner cavity of the mineralizer cylinder 5, are located on the top cover of the mineralizer cylinder 5.

[0060] Under the trend of circulation, some gas does not adhere to the mineral particles, but directly forms bubbles and gathers towards the center and top, causing the gas pressure inside the mineralizer cylinder 5 to increase. The top cover generally does not come into contact with the molten mineral and is usually a weak point in the design of the mineralizer cylinder 5. Therefore, in this embodiment, the top cover is set to be spherical to reduce the occurrence of stress concentration and improve service life.

[0061] The mineralized slurry can be collected from the mineralizer cylinder 5 through the ore outlet 14, and the gas outlet 13 is used to remove excess gas.

[0062] In one embodiment, vortex and vortex generators 7 are provided between adjacent annular baffles 6, and the vortex and vortex generators 7 are distributed along the inner wall of the mineralizer cylinder 5; the vortex and vortex generators 7 include elongated baffles, slotted baffles, serrated baffles, triangular airfoil baffles, trapezoidal baffles, and / or arc-shaped guide baffles;

[0063] The closer to the bottom of the mineralizer cylinder 5, the stronger the turbulence design performance of the vortex and vortex generator 7, which in turn promotes the adhesion of mineral particles and bubbles. In the area far away from the mineralizer cylinder 5, a large amount of slurry has already been mineralized. At this time, excessive turbulence will cause bubbles to separate from mineral particles. The further away from the bottom of the mineralizer cylinder 5, the weaker the turbulence design performance of the vortex and vortex generator 7.

[0064] As one embodiment, turbulence dissipation rate can be selected as the turbulence design performance parameter to be considered during the design process.

[0065] In one embodiment, the chamber 17 includes a third chamber 17-4 located at the top of the mineralizer cylinder 5 and a first chamber 17-2 located at the bottom of the mineralizer cylinder 5; the stirring blades include a third stirring impeller 8 located in the third chamber 17-4 and a first stirring impeller 11 located in the first chamber 17-2; both the first stirring impeller 11 and the third stirring impeller 8 include vertical stirring blades radially distributed around the stirring shaft 9.

[0066] The vertical stirring blades have a better stirring effect. The first stirring impeller 11 and the third stirring impeller 8, located at the upper and lower ends of the mineralizer cylinder 5, stir simultaneously, which can better promote the overall circulation.

[0067] In one embodiment, the chamber 17 further includes a second chamber 17-3 located between the first chamber 17-2 and the third chamber 17-4; the stirring blade includes a second stirring impeller 10, which includes two layers of paddle-type stirring blades facing the first chamber 17-2 and the second chamber 17-3 respectively, and the paddle-type stirring blades are radially distributed with the stirring shaft 9 as the center.

[0068] The circulation generated by the paddle-type stirring blades can be coupled with the first stirring impeller 11 and the third stirring impeller 8 at the upper and lower ends.

[0069] In one embodiment, the mineralizer cylinder 5 includes a fourth chamber 17-1 formed by the lifting and guiding annular cavity 16; the first stirring impeller 11 further includes a spiral guide vane 11-1 and a first vertical stirring vane 11-2, the spiral guide vane 11-1 being located on the side away from the fourth chamber 17-1, and the first vertical stirring vane 11-2 being located on the side close to the fourth chamber 17-1; the spiral guide vane 11-1 is used to generate a lifting flow coupled with the guiding direction of the lifting and guiding annular cavity 16.

[0070] In one embodiment, the stirring shaft 9 is connected to the frequency converter 1 via a coupling 3, and the frequency converter 1 is connected to the frequency converter motor reducer 2; the coupling 3 is connected to the mineralizer cylinder 5 via a mounting base plate 4.

[0071] The rotational speed of the agitator shaft 9 can be adjusted by the frequency converter 1 for different types of gaseous slurry.

[0072] This embodiment also provides a corresponding usage method:

[0073] In response to the acquisition of a mineralization start signal, a transition liquid is injected into the mineralizer cylinder 5 through the inlet 12;

[0074] In response to the transition liquid level reaching the liquid level threshold, the injection of the transition liquid is stopped, and gaseous slurry is injected into the mineralizer cylinder 5 through the ore inlet 12, while the stirring device is started.

[0075] In response to the mineral concentration at outlet 14 being lower than the concentration threshold, the stirring device is shut down.

[0076] The pre-injection of transition liquid is to protect the variable frequency motor reducer 2. As one embodiment, the gaseous slurry can be directly injected through the ore inlet 12. When the mineral concentration at the ore outlet 14 is lower than the concentration threshold, it can be considered that the batch of slurry has been basically processed, and the stirring device is turned off.

[0077] As one embodiment, a controller and multiple sensors can be installed in the pressure-confined high-energy-state conditioning and mineralization integrated device. The sensors, variable frequency motor reducer 2 and frequency converter 1 are respectively connected to the controller by electrical signals, so that the controller can execute the above method.

[0078] In one embodiment, the conical bottom of the lifting and guiding annular cavity 16 guides and lifts the slurry entering the bottom of the mineralizer cylinder 5, preventing the slurry from stagnating and depositing at the bottom. It also allows the slurry to quickly enter the upper confined mineralization zone under the auxiliary entrainment of the spiral guide vanes 11-1. An inlet 12 is provided on the lower side wall of the mineralizer cylinder 5, and the inlet 12 communicates tangentially or nearly tangentially with the interior of the mineralizer cylinder 5. After the gas-laden slurry enters through the inlet 12, it forms a circumferential swirling flow along the inner wall of the mineralizer cylinder 5. This swirling flow enhances the dispersion and suspension of the slurry in the lower part of the mineralizer cylinder 5, and together with the conical bottom of the lifting and guiding annular cavity 16, forms an upward lifting flow, giving the slurry an upward transport tendency from the initial stage of entering the equipment, reducing energy consumption caused by relying solely on impeller lifting.

[0079] In one embodiment, three annular baffles 6 are arranged along the height direction inside the mineralizer cylinder 5, namely the first annular baffle 6-1, the second annular baffle 6-2, and the third annular baffle 6-3. Each annular baffle 6 has a central opening, which is coaxially arranged with the stirring shaft 9, allowing the slurry to pass through the central opening under the action of the impeller, thus achieving communication between the upper and lower chambers 17. The three annular baffles 6 divide the interior of the mineralizer cylinder 5 into four interconnected confined mineralization zones. Compared with the traditional undivided cylinder, this embodiment restricts the slurry to form a single continuous large circulation inside the mineralizer cylinder 5 through the annular baffles 6, causing the slurry to form local circulation, local backflow, and local disturbance in each confined zone, i.e., each chamber 17, thereby extending the effective residence path of the slurry inside the mineralizer cylinder 5 and increasing the opportunity for repeated contact between particles and bubbles.

[0080] In one embodiment, the annular baffle 6 not only functions as a cavity divider but also as a flow field remodeling unit. The annular baffle 6 is provided with a slit structure, which can be arranged on the surface of the annular baffle 6, at the edge of the central opening, in the area near the cylinder wall, or in adjacent flow areas. Preferably, the slits are serrated. When the slurry passes through the central opening and the serrated slits of the annular baffle 6, the fluid is locally contracted and cut, forming multiple fluid separation points and shear interfaces at the edge of the serrations, thereby generating local jets, wake vortices, and small-scale vortices. Thus, the annular baffle 6 is no longer just a simple partition but also functions as a confined cavity divider, a local acceleration unit, a fluid shearing unit, and a micro-vortex generator. Through this structure, some energy in the large-scale swirling flow and impeller circulation can be converted into small-scale micro-vortices, increasing the local energy dissipation intensity within the cylinder and resulting in more sufficient fluid disturbance near the particle-bubble interface.

[0081] In one embodiment, the vortex and swirl generator 7 can be a VG vortex generator arranged on the inner wall of the mineralizer cylinder 5. The vortex and swirl generator 7 is fixedly installed along the inner wall of the cylinder and can adopt a long strip-shaped baffle, a slotted baffle, a sawtooth-edged baffle, a triangular airfoil baffle, a trapezoidal baffle, an arc-shaped guide baffle, or other structural forms that can induce local vortices in the fluid. The vortex and swirl generator 7 is located in the confined mineralization area between adjacent annular baffles 6. When the gas-laden slurry rotates and flows along the inner wall of the mineralizer cylinder 5, the vortex and swirl generator 7 can cut the near-wall flow, causing the fluid boundary layer to separate, and forming longitudinal vortices, wake vortices, and local backflow zones behind the vortex and swirl generator 7. Through the combined action of the eddy current and the slits set on the vortex generator 7 and the annular baffle 6, high-energy micro-vortices can be formed near the inner wall of the mineralizer cylinder 5 and in the flow area of ​​the annular baffle 6, causing microbubbles and mineral particles to be continuously disturbed and redispersed in multiple spatial locations.

[0082] To enable different mineralization functions in different height zones, this embodiment can configure the vortex and vortex generator 7 near the wall of the lower chamber 17 with a larger inclination angle, larger opening, or stronger turbulence structure to form a high-energy dissipation and strong micro-vortex region. This region corresponds to the initial mineralization stage after the gaseous slurry enters the equipment, mainly used to enhance bubble crushing, particle suspension, and high-frequency collisions between particles and bubbles. The vortex and vortex generator 7 near the wall of the upper chamber 17 can be configured with a smaller inclination angle or a gentler turbulence structure to maintain uniform slurry flow and moderate circulation, preventing the already formed particle-bubble mineralized body from being subjected to excessive shear and desorption. Through the above arrangement, the internal flow field is divided into functional zones from bottom to top, namely, a lower high-energy mineralization zone, a middle circulation and re-collision zone, and an upper stable flow discharge zone, thus taking into account both enhanced collision and stable adhesion processes.

[0083] A stirring shaft 9 is vertically positioned at the center of the mineralizer cylinder 5. From bottom to top, a third stirring impeller 8, a second stirring impeller 10, and a first stirring impeller 11 are sequentially mounted on the stirring shaft 9. The first stirring impeller 11 is positioned above the lifting and guiding annular cavity 16, primarily used to work in conjunction with the lifting and guiding annular cavity 16 to entrain the gaseous slurry entering tangentially from the inlet 12 and transport it upwards to the lower confined mineralization zone. The first stirring impeller 11, together with the tangential inlet 12 and the lifting and guiding annular cavity 16, creates a swirling lifting and upward circulation of the slurry at the bottom, thereby preventing bottom sedimentation and enhancing initial dispersion. The second stirring impeller 10 is positioned in the middle confined zone, used to maintain the circulation transport between the confined chambers, allowing the slurry to pass through the central opening and slit area of ​​the annular baffle 6 multiple times, achieving repeated shearing and redispersion. The first stirring impeller 11 is located in the upper confined area and is used to stabilize, homogenize, and adjust the flow state of the gas-containing slurry entering the upper chamber before discharge, so as to make the gas-liquid-solid three-phase distribution more stable.

[0084] A gas outlet 13 is provided at the top or upper part of the mineralizer cylinder 5, and a ore outlet 14 is provided on the upper side. The gas outlet 13 is used to discharge the gas accumulated in the upper part of the mineralizer cylinder 5 and to assist in the regulation of the internal pressure of the mineralizer cylinder 5. Since this device processes gaseous slurry, bubbles will locally accumulate in the upper region during operation. If they are not discharged in time, it can easily cause gas resistance, pressure fluctuations, foam backmixing, or discontinuous discharge from the ore outlet. In this embodiment, by setting the gas outlet 13, the gas accumulated in the upper chamber can be discharged, thereby maintaining the stability of the internal pressure of the mineralizer cylinder 5. The ore outlet 14 is used to discharge the mineralized slurry and transport it to the subsequent flotation equipment. The gas outlet 13 and the ore outlet 14 work together to enable the device to operate continuously and stably under pressurized gaseous slurry conditions.

[0085] In this embodiment, during operation, the gaseous slurry enters tangentially into the lower part of the mineralizer cylinder 5 through the inlet. Upon entry, the slurry first forms a swirling flow along the inner wall and moves towards the center and upper part under the guidance of the lifting and guiding annular cavity 16. The spiral guide 11-1 entrains and lifts the slurry entering the bottom, causing the gaseous slurry to enter the lower confined mineralization chamber, i.e., the first chamber 17-2. At this time, the eddies on the lower wall, together with the vortex generator 7 and the serrated openings of the annular baffle 6, generate high-energy dissipation small-scale eddies. Large bubbles are sheared and broken into microbubbles, and mineral particles frequently collide with and adhere to the bubbles under the action of the swirling flow, micro-vortices, and impeller projection. Subsequently, under the action of the second stirring impeller 10, the slurry passes through the central opening of the annular baffle 6 and enters the middle confined chamber, i.e., the second chamber 17-3, where it continues to undergo reflux, redispersion, and re-collision processes. After the slurry further enters the upper chamber, namely the third chamber 17-4, the third stirring impeller 8 stabilizes and homogenizes it, while the gas outlet 13 discharges the enriched gas from the upper chamber. Finally, the mineralized slurry is discharged from the outlet 14.

[0086] Through the aforementioned structure and operation, this embodiment creates a continuous process within a vertical cylinder: "tangential feed vortex—conical bottom lifting—lower high-energy micro-vortex mineralization—middle circulation and re-collision—upper stable flow and venting discharge," allowing the gas-laden slurry to obtain multiple effective mineralization opportunities within a limited space. Compared to existing conventional mechanically agitated mineralizers, this embodiment not only improves bubble refinement efficiency and particle-bubble collision probability but also reduces short-circuit flow, dead zones, and air resistance within the cylinder, enhancing the stability and continuity of the mineralization process before flotation of fine-grained minerals.

[0087] The bubble mineralization device provided in this embodiment, through a combination of structural elements such as tangential feeding, conical bottom guiding and lifting, multi-stage annular baffles 6 for confining and dividing the cavity, sawtooth slit high-energy dissipation, wall-mounted VG vortex generator for turbulence, multi-stage stirring impeller coordination, and pressure stabilization and exhaust at the outlet, forms a continuous and stable multi-flow coupled mineralization environment within a limited cylindrical space. Compared with existing conventional mechanical stirring mineralization equipment, this embodiment can improve the initial flow field intensity after the gaseous slurry enters the cylinder. In this embodiment, the inlet 12 is set to a tangential or near-tangential feeding method, so that the gaseous slurry can form a rotating flow along the inner wall of the cylinder after entering the mineralizer cylinder 5. Compared with the conventional radial feeding method, tangential feeding can directly convert the kinetic energy of the feed into circumferential swirling kinetic energy, so that the slurry forms a swirling dispersion state in the early stage of entering the cylinder, reducing local impact flow and short-circuit flow, and improving the dispersion uniformity of the slurry in the lower part of the cylinder. The bottom of the mineralizer cylinder 5 is designed with a conical structure. After the gaseous slurry enters tangentially, it moves towards the center and upward under the guiding effect of the conical bottom. At the same time, the third stirring impeller 8 generates a suction and lifting effect on the slurry at the bottom. This structure can prevent particles from staying at the bottom of the cylinder for a long time, reduce sedimentation, material accumulation and dead zones, and improve the continuous operation stability of high-concentration slurry or slurry containing coarse particles. In this embodiment, the interior of the mineralizer cylinder 5 is divided into four interconnected confined mineralization chambers by three layers of centrally perforated annular baffles 6. The slurry cannot be directly short-circuited from the inlet to the outlet in the cylinder. Instead, it needs to pass through the central openings and slit areas of each level of annular baffles 6 in sequence, and repeatedly undergo circulation, backflow, redispersion and recollision processes in different chambers 17, thereby extending the effective contact path between particles and air bubbles and improving the utilization efficiency of slurry residence time. A serrated slit structure is installed on the annular baffle 6. When the slurry passes through the central hole and the serrated slits, the fluid is subjected to local contraction, cutting, and shearing, forming multiple fluid separation points and shear interfaces at the edge of the serrations, inducing the formation of local jets, wake vortices, and small-scale vortices. This structure can convert part of the energy in the large-scale swirling flow and impeller circulation flow into small-scale vortex energy, increasing the intensity of local disturbances near the particle-bubble interface. Vortex and vortex generators 7 are arranged on the inner wall of the mineralizer cylinder 5. When the slurry rotates and flows along the inner wall of the cylinder, the vortex and vortex generators 7 can cut the near-wall fluid, causing the fluid boundary layer to separate and forming longitudinal vortices, wake vortices, and local backflow zones behind it. This avoids the formation of a stable low-velocity layer near the cylinder wall, improves the slurry renewal capacity in the near-wall region, and makes the distribution of particles and bubbles in the radial direction of the cylinder more uniform. After the gas-laden slurry enters the cylinder, it is simultaneously subjected to multiple effects, including tangential swirling, shearing by the first stirring impeller 11, cutting by the serrated opening of the annular baffle 6, and micro-vortex disturbance by the vortex generator 7. This causes large bubbles to continuously stretch, deform, and break down, forming a larger, smaller, and more uniformly distributed cluster of microbubbles. These microbubbles have a larger total specific surface area and a higher chance of particle contact, which is beneficial for improving the efficiency of subsequent particle-bubble mineralization.Fine mineral particles, due to their small mass and weak inertia, struggle to actively break through streamlines and effectively collide with bubbles in ordinary flow fields. This embodiment utilizes small-scale micro-vortices, localized recirculation, and multi-stage impeller circulation to continuously subject particles to entrainment, projection, lateral migration, and recirculation, increasing the relative velocity and contact frequency between particles and bubbles, thereby enhancing the probability of effective collisions between fine particles and bubbles. This embodiment creates a high-energy micro-vortex mineralization environment in the lower region, strengthening bubble refinement and initial particle-bubble collisions; a circulating re-collision environment in the middle region, allowing insufficiently mineralized particles multiple contact opportunities; and a relatively stable homogenized discharge environment in the upper region, reducing the possibility of detachment from already formed mineralized bodies due to severe shearing. This enhances collisions while maintaining mineralized body stability, improving particle-bubble adhesion efficiency. The first impeller 11 primarily performs bottom entrainment, lifting, and initial dispersion functions; the second impeller 10 primarily performs inter-chamber circulation and redispersion functions; and the third impeller 8 primarily performs upper flow stabilization, homogenization, and pre-discharge flow pattern adjustment functions. The three-stage impeller, in conjunction with the annular baffle and the wall-mounted VG, creates a lower high-energy mineralization zone, a middle circulation enhancement zone, and an upper stable discharge zone within the mineralizer. This avoids the problems of unclear flow field function and unreasonable energy distribution in traditional single-impeller equipment. Since this embodiment processes gaseous slurry, gas accumulation is likely to occur in the upper part of the cylinder during operation. By setting the vent 13, the accumulated gas in the upper part can be discharged in a timely manner, reducing pressure fluctuations within the cylinder and preventing gas blockage, foam backmixing, or discontinuous discharge at the outlet. The vent 13 works in conjunction with the outlet 14, enabling the device to achieve stable and continuous discharge under pressurized gaseous slurry conditions. The annular baffle 6 and the vortex generator 7 work together to suppress the formation of a single, stable, large-scale ineffective circulation within the cylinder, causing the fluid to continuously change direction, distribute energy, and transform scale as it passes through the baffle openings, sawtooth gaps, and VG turbulence zone. This structure helps convert the energy from mechanical stirring and feed kinetic energy into smaller-scale disturbance energy that is more effective for bubble refinement, particle suspension, and particle-bubble mineralization. This embodiment significantly increases the interaction opportunities between fine particles and microbubbles through the combined effects of tangential swirling lifting, confined chamber design, multi-stage impeller circulation, and micro-vortex enhancement. This allows fine mineral particles to form a more complete and stable mineralization state before entering subsequent flotation equipment, thereby improving subsequent flotation recovery and separation efficiency. This embodiment has a compact structure, integrating feed swirling, bottom anti-deposition, chamber confinement, micro-vortex enhancement, bubble refinement, stable flow venting, and continuous discharge functions into a single mineralizer cylinder. By adjusting the inverter output frequency, it can adapt to different pulp concentrations, feed flow rates, aeration rates, and particle size distributions, exhibiting good adaptability for continuous industrial operation.

[0088] In one embodiment, the angle between the centerline of the inlet 12 and the tangential direction of the cross-section of the mineralizer cylinder 5 is 0° to 30°, more preferably 0° to 15°. After the gaseous slurry enters the cylinder through the inlet 12, it forms a circumferential swirling flow along the inner wall of the cylinder and moves upward under the guidance of the conical bottom, thereby forming an initial flow state of "tangential swirling flow + conical bottom lifting".

[0089] In summary, this embodiment achieves efficient dispersion, bubble refinement, micro-vortex enhancement, and continuous mineralization of gaseous slurry in a confined space through a combined design of "tangential ore feeding—cone bottom lifting—confined cavity division—serrated dissipation—wall vortex generation—multi-stage stirring—venting and pressure stabilization." It can effectively improve the mineralization efficiency of fine-grained minerals and bubbles, and improve the operational stability of the equipment.

[0090] As one embodiment, reference Figure 6 , Figure 7 and Figure 8 The stirring shaft 9 is fitted with a first chamber concentrate collection plate 15-1 and a second chamber concentrate collection plate 15-2. The first chamber concentrate collection plate 15-1 is located at the top of the second chamber 17-3 and is connected to the first independent discharge pipe 16-1. The second chamber concentrate collection plate 15-2 is located at the top of the first chamber 17-2 and is connected to the second independent discharge pipe 16-2. The first chamber concentrate collection plate 15-1 and the second chamber concentrate collection plate 15-2 adopt an annular disc shape, a shallow groove shape, or a disc shape with a central clearance hole. The bottom of the first chamber concentrate collection plate 15-1 and the second chamber concentrate collection plate 15-2 is provided with multiple collection holes, which are round holes, oblong holes, or strip-shaped holes.

[0091] The central openings of the first chamber concentrate collection tray 15-1 and the second chamber concentrate collection tray 15-2 are used to avoid the stirring shaft 9 and related stirring components. These collection holes can be round, oblong, strip-shaped, or other flow-through structures that allow for concentrate introduction. During mineralization, the particle-bubble mineralized bodies formed in each confined mineralization chamber are enriched towards the upper part of the chamber under the action of buoyancy, swirling flow, and local backflow. They then enter the interior of the trays through the collection holes at the bottom of the first chamber concentrate collection tray 15-1 and the second chamber concentrate collection tray 15-2, forming temporary accumulation and buffer enrichment areas within the trays. The concentrate or mineralized foam inside the first chamber concentrate collection tray 15-1 and the second chamber concentrate collection tray 15-2 are discharged separately through the corresponding first independent discharge pipe 16-1 and second independent discharge pipe 16-2, thereby achieving independent collection and segmented discharge of the concentrate enriched in different confined mineralization chambers. By setting up a chambered concentrate collection tray with collection holes and its independent discharge pipe, this embodiment can form a concentrate collection path of "internal mineralization - upper enrichment - tray collection - independent discharge". This allows the formed concentrate to be discharged in a timely manner at the corresponding mineralization stage, reducing the repeated circulation and secondary shearing of mineralized particles in the subsequent high-energy flow field, and reducing the possibility of particle-bubble mineralization desorption. At the same time, the concentrates from different chambers can be discharged separately, providing conditions for independent sampling, classification evaluation and subsequent processing of products at different mineralization stages, thereby improving the mineralization selectivity, operational controllability and continuous operation capability of the device.

[0092] refer to Figure 9 , Figure 9 In sections a, b, c, and d, the lower white component is a cross-section of the first stirring impeller 11, and the two smaller white components in the upper section are cross-sections of the second stirring impeller 10. After the slurry enters the mineralizer, it mainly relies on the various stirring impellers to generate circulating flow and local high-speed jets to achieve bubble dispersion and collision mineralization between particles and bubbles. However, without the wall disturbance structure, i.e., the vortex and eddy generator 7, the mechanical energy input by each impeller is mainly concentrated near the impeller and in its radial jet region. As the fluid moves towards the cylinder wall and away from the impeller, the velocity gradually decreases, easily forming a relatively smooth large-scale circulating flow. For the mineralization of fine-grained minerals, simply forming a large-scale macroscopic circulation is not enough to fully meet the requirements of particle-bubble interaction. This embodiment believes that, while maintaining the overall circulating transport capacity of the impeller, it is necessary to further utilize the cylinder wall structure to actively disrupt and reconstruct the impeller jet, so that some of the large-scale flow energy is converted into local velocity gradients and small-scale disturbances. Therefore, a vertical eddy current and vortex generator 7 with a serrated baffle structure was added to the inner wall of the mineralizer cylinder 5, and the two schemes of setting baffles and not setting baffles were compared and analyzed by CFD simulation.

[0093] To investigate the effect of the vertical serrated baffle on the internal flow field of the mineralizer, two calculation models were established while keeping the mineralizer cylinder dimensions, impeller structure, impeller speed, medium properties, and other boundary conditions consistent:

[0094] Option 1 is a mineralizer structure with vertical serrated baffles, that is, vertical baffles with serrated turbulence edges are arranged along the axial direction on the inner wall of the mineralizer.

[0095] Option 2 is a control structure without vertical serrated baffles, while other geometric dimensions and operating parameters remain the same as Option 1.

[0096] The velocity distributions of the two phase media were obtained separately to compare the effects of the serrated baffle on impeller jet expansion, near-wall flow, velocity gradient, and velocity field distribution inside each chamber.

[0097] To investigate the effect of the vertical serrated baffle on the internal flow field of the mineralizer, two calculation models were established while keeping the mineralizer cylinder dimensions, impeller structure, impeller speed, medium properties, and other boundary conditions consistent:

[0098] Option 1 is a mineralizer structure with vertical serrated baffles, that is, vertical baffles with serrated turbulence edges are arranged along the axial direction on the inner wall of the mineralizer.

[0099] Option 2 is a control structure without vertical serrated baffles, while other geometric dimensions and operating parameters remain the same as Option 1.

[0100] The velocity distributions of the two phase media were obtained separately to compare the effects of the serrated baffle on impeller jet expansion, near-wall flow, velocity gradient, and velocity field distribution inside each chamber.

[0101] Figure 9 (a) and Figure 9 In the structure without vertical serrated baffles shown in (b), the high-speed region generated by the impeller is also concentrated near the impeller, but the velocity field formed by the outward expansion of the impeller is more continuous and smooth overall. As the distance from the impeller increases, the velocity mainly shows a continuous decay trend. The near-wall region lacks geometric structures that can actively cut the fluid, so the degree of flow field reconstruction between the impeller jet and the cylinder wall is relatively weak. Its overall flow is more likely to exhibit a large-scale circulation dominated by the impeller, while the wall region has a limited effect on the redistribution of flow field energy.

[0102] In comparison, Figure 9 (c) and Figure 9(d) shows the velocity contour maps of the two-phase media under the condition of setting vertical serrated baffles. It can be seen that the high-speed zone inside the mineralizer is mainly formed at the outer edge of the impeller blades and in the radial jet direction, with the high-speed zone formed by the first vertical stirring blade 11-2 being the most obvious, and the local velocity reaching the high value zone of the velocity range shown in the figure. After the high-speed jet extends to both sides of the cylinder, it interacts with the serrated baffles on the wall, causing a significant velocity redistribution in the radial jet that was originally continuously developing in the area near the wall.

[0103] Particularly in the region near the sawtooth baffle, the velocity contour lines exhibit more pronounced bending, compression, and local segmentation, indicating that the sawtooth structure on the wall exerts a continuous disturbance on the near-wall fluid. After impacting or passing over the sawtooth structure, the main jet generated by the impeller no longer simply forms a continuous large-scale flow along the wall; instead, it undergoes local deflection, splitting, and re-merging, resulting in a more complex velocity gradient distribution. This flow field characteristic facilitates increased momentum exchange between the main flow region and the near-wall region, providing hydrodynamic conditions for subsequent local shearing, fluid separation, and small-scale vortices.

[0104] A comparison of the two structures reveals that the addition of vertical serrated baffles does not alter the fundamental flow pattern of the impeller as the main source of circulating power. Instead, it modulates the propagation and energy distribution of the impeller jet. Specifically, the impeller first generates a high-speed radial jet and axial circulation. The jet then interacts with the serrated wall structure, resulting in flow splitting, reversal, and enhanced local velocity gradients, thus forming a multi-scale flow process: "impeller main circulation – wall secondary disturbance – local flow field reconstruction."

[0105] also, Figure 9 The main high-speed and low-speed regions of the two-phase medium generally correspond in location, indicating that the main flow field characteristics formed by the impeller and wall structure can simultaneously act on the two-phase medium within the mineralizer. After the serrated baffle is installed, both phases exhibit the characteristic of remodulating the velocity distribution in the near-wall region, indicating that the structure can exert a flow field regulation effect on the overall multiphase flow, rather than acting only on a single fluid phase.

[0106] Based on the above CFD comparison results, this embodiment ultimately retains the vortex and vortex generator 7 with a vertical serrated baffle structure. Its design purpose is not simply to block the overall rotation of the fluid, but to use the serrated edges to form multiple periodic flow separation points, so that the large-scale high-speed flow generated by the impeller is continuously cut and disturbed when it propagates to the vicinity of the cylinder wall.

[0107] The resulting design process can be summarized as follows:

[0108] The impeller provides the main circulation and high-speed jet → the high-speed flow extends to the cylinder wall → the serrated baffle cuts, deflects and redistributes the jet → enhances the local velocity gradient and near-wall momentum exchange → creates conditions for high energy dissipation and small-scale vortex formation → strengthens the relative motion between particles and bubbles and mineralization.

[0109] Therefore, the vertical serrated baffle is not an ordinary anti-swirl baffle, but rather an active flow field control unit inside the mineralizer, which together with the impeller, the annular baffle 6 and the confined chamber forms a multi-flow-state coupled mineralization environment.

[0110] In further numerical analysis of this embodiment, the changes in local high-energy regions before and after the vertical serrated baffle can be quantitatively compared by combining turbulent dissipation rate, turbulent kinetic energy or vorticity distribution, so as to further prove that the structure can promote the transfer of large-scale flow energy to small-scale flow structure and provide a more suitable local hydrodynamic environment for micro-particle-bubble enhanced mineralization.

[0111] The CFD comparison design of the above "baffle-less structure - serrated baffle structure" shows that the structural form and arrangement of the vertical serrated baffle in this embodiment are derived from the targeted optimization of the internal flow field of the mineralizer, rather than the arbitrary setting of conventional baffles.

[0112] The final determined serrated baffle structure can perform secondary regulation of radial jet and near-wall flow while retaining the macroscopic transport capacity of the impeller. This allows the mineralizer to simultaneously have large-scale circulating transport and local small-scale flow enhancement characteristics, thus matching the design concept of "multi-flow-state coupling enhanced mineralization in confined space" proposed in this embodiment.
