Description

Technical Field

[0001] The invention relates to the technical field of jigging magnetic flotation columns, in particular to a jigging magnetic flotation column. Background Art

[0002] With the rise of new high-efficiency column-type electromagnetic and gravity beneficiation equipment represented by elutriation magnetic separators, electromagnetic and gravity concentration technologies and processes for magnetic iron ore have been widely used. Compared with drum magnetic separators, the concentrate grade can be greatly improved under the same feeding conditions and yield conditions. In some cases, it can completely replace the reverse flotation process of magnetite. However, when elutriation magnetic separators are used in occasions such as magnetic hematite, pyrrhotite and titanomagnetite, the effect of mineral separation completely relying on magnetic and gravity differences will be affected for occasions where the magnetic and density differences of mineral particles are not large. For example, magnetite particles are generally associated with gangue, phosphorus, sulfur, titanium and other ores. Therefore, crushing and grinding are required before beneficiation to separate magnetic iron particles from non-magnetic ore particles, which is professionally called analysis. Then use magnetic separation equipment for separation. Because no matter how finely the ore is ground, there are still unground intergrowth particles, that is to say, among the intergrowth particles, there are some magnetite and some non-magnetic minerals. The iron-rich particles have relatively strong magnetism and high iron grade, which are called rich intergrowth, and vice versa, which are called poor intergrowth. Generally, when selecting ore, it is hoped to retain the rich intergrowth into the concentrate and discard the poor intergrowth into the tailings, so that a higher grade concentrate can be obtained without affecting the recovery rate of iron products due to discarding the rich intergrowth particles. However, since both have different strengths of magnetism, when using ordinary magnetic separators with strong magnetic fields, both intergrowths will be adsorbed into strong magnetite and become iron concentrate, which often leads to the failure to obtain high-grade iron concentrate.

[0003] In addition, the traditional flotation method mainly uses two types of flotation machines with mechanical stirring devices and non-stirring flotation columns. The flotation foam is used to adhere to the hydrophobic particle minerals from the slurry surface and recover the foam to achieve the separation of useful minerals and useless gangue minerals. The bubbles float up with a certain thickness of slurry layer, gradually gather and interfere with each other when reaching the foam layer, and continue to rise at a certain speed after leaving the slurry surface into the foam layer. The problem is that setting a static separation zone can stabilize the liquid surface and the thickness of the foam layer. The slurry flow rate in the static separation zone is low, the momentum of the particle mineral in the slurry is small, and the probability of collision with the bubbles is low. The fine particle mineral is seriously non-selectively agglomerated in the flotation column, which affects the selectivity of flotation. The coarse particle mineral is not easy to suspend, the probability of collision with the bubbles is low and it is very easy to fall off the bubbles, resulting in low flotation recovery, low concentrate grade, and the need for multi-stage separation. Ordinary flotation columns require static separation zones and stable beds, which lead to insufficient momentum of mineral particles. Especially for the separation of coarse particles and ultrafine particles with wide particle sizes, the flotation process cannot obtain ideal indicators even if the dosage of reagents is increased. In particular, the key point is that the ordinary flotation process uses reagents as inhibitors. Even for magnetic iron minerals with good floatability, such as pyrrhotite, due to the poor inhibition effect during the flotation process, a large amount of pyrrhotite will float in the foam. This seriously restricts the improvement of flotation efficiency and single-machine processing capacity, and increases equipment investment and production consumption. At the same time, due to the separation of mineralized bubbles from the slurry surface, dehydration of the foam layer, bubble merger and crushing, the gas-liquid interface is reduced, and the unattached or loosely attached mineral particles fall and return to the slurry, so that a large amount of target minerals are enriched below the slurry surface and cannot be recovered in time, resulting in low mineral flotation rate and recovery rate. In the existing mineralizer, conventional stirring impellers are used for stirring, and the stirring rod cannot stir the ore at different heights inside the mineralizer, so it needs to be improved.

[0004] In addition, the existing technology uses a magnetic flotation column developed by adding bubble flotation to a washing magnetic separator or a magnetic column. Since the washing magnetic separator needs to wash the pulp with flushing water, the tailings concentration is low (generally less than 5%). If the flotation agent is directly added, the agent is diluted by the flushing water, resulting in the loss of the flotation agent and poor flotation effect. Summary of the invention

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. The jigging magnetic flotation column, through the stirring mechanism, when it is necessary to stir the ore inside the mineralizer, the stirring motor, the rotating shaft and the stirring plate are used in combination, so that the stirring plate can stir the ore inside the mineralizer. When it is necessary to adjust the stirring position of the stirring plate, the driving motor, the worm, the worm gear, the threaded rod, the lifting plate and the load-bearing frame are moved upward, so that the load-bearing frame can drive the stirring motor to move upward, so that the stirring motor can drive the stirring plate to move upward through the rotating shaft, so that the stirring height of the stirring plate can be adjusted, so that the device can stir the ore at different heights inside the mineralizer, and the stirring helps the ore and the chemical to be mixed evenly inside the mineralizer. The even mixing can make each ore particle fully contact the reagent, thereby improving its flotation efficiency.

[0022] 2. The jigging magnetic flotation column, through the feeding mechanism, is used in conjunction with the feeding pipe, feeding pump, bulk barrel, bulk feeder, doser, transmission pipe and conveying pipe, so that the conveying pipe can convey the mineral material to the inner barrel, and the material is evenly sprinkled inside the inner barrel through the bulk feeder.

[0023] 3. The jigging magnetic flotation column uses a pulsating mechanism to feed the slurry from the feeding port to the feeding mechanism, and then to the inner tube through the conveying pipe for dispersion. The pulsating disk cooperates with the connecting rod and the driver to generate pulsating slurry flow through periodic reciprocating motion. This pulsating slurry flow forms a vertical alternating slurry flow force in the jigging magnetic flotation column, so that the mineral particles entering the separation tank can be re-stratified under the action of the vertical alternating medium flow;

[0024] Different from the existing flotation machine that needs to construct a turbulent flotation zone and a static separation zone that are physically isolated from each other and a stable foam layer, and different from the existing magnetic flotation machine that must add a flushing water flow, which causes the flotation reagent to be diluted, affects the flotation effect, wastes the flotation reagent, and increases the amount of reagent used, the present invention does not need to form a clear pulp-foam interface and foam layer in the static flotation area, allows the tailings pulp and mineralized bubbles to overflow through the overflow weir together, realizes dynamic flotation, solves the technical problem that the washing magnetic separator needs to use a large amount of flushing water while the addition of water to the flotation column affects the concentration of the reagent, makes it possible to apply the magnetic flotation composite beneficiation method to magnetite, synchronously and reversely adjusts the separation magnetic field intensity, solves the problem of overflow tailings running black and magnetic inclusions in magnetic concentrate caused by jigging pulsation, prevents the occurrence of flotation column pulp running out of the trough and ore leakage and washing magnetic separator running black and ore leakage, and also improves the product recovery rate and concentrate index. In particular, unlike ordinary static flotation devices, the present invention does not have the "pure foam layer" of traditional flotation methods, but uses the reciprocating motion of the pulsating jigging device to deform the magnetic flotation column cavity and change the volume, further causing the pulsation of the ore pulp flow inside the magnetic flotation column cavity and the pulsation change of the overflow liquid level. The pulsation of the ore pulp flow inside the magnetic flotation column cavity enhances the flotation mineralization effect and the separation effect of the magnetic field on magnetic particles, non-magnetic particles and weakly magnetic particles. The pulsating change of the overflow liquid level allows the mineralized bubbles attached to the hydrophobic particles and the hydrophobic particles and impurities enriched below the liquid surface after the bubbles burst to have the opportunity to jump over the overflow weir in time and enter the overflow tank to form a continuous overflow. The controllability of the flotation tailings is enhanced. On the one hand, the jigging pulsation mechanism + flotation process solves the dependence of ordinary washing magnetic separators or magnetic separation columns on the use of flushing water. On the other hand, it also solves the problem that when ordinary washing magnetic separators are used to select hematite, pyrrhotite and titanomagnetite, the grade of iron concentrate meets the standard while some harmful impurities exceed the standard due to the small difference in magnetic properties and density between the iron concentrate and harmful mineral particles.

[0025] 4. The jigging magnetic flotation column, through the microbubble generating mechanism, opens the high-pressure gas source and the servo valve, so that the servo valve can inhale the compressed air and transfer it to the inside of the gas-splitting tube, and transmit the gas to the inside of the microbubble generator through the gas-splitting tube. Since the gas-splitting tube provides a stable gas supply for the microbubble generator, the microbubble generator can continuously and efficiently generate a large number of fine bubbles. The sufficient supply ensures that the jigging magnetic flotation column device can process more ore particles, thereby enhancing the flotation effect and improving the processing capacity of the equipment.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides the following technical solutions:

[0036] Embodiment 1:

[0037] Combination Figures 1 to 3 A jigging magnetic flotation column includes an inner cylinder 100, an excitation coil 200 is fixedly connected to the periphery of the inner cylinder 100, and an outer cylinder 1001 is arranged around the excitation coil 200; a conical concentrator 1004 is fixedly connected to the bottom of the inner cylinder 100, a pulsating mechanism 400 is arranged on one side of the conical concentrator 1004, and the inner cylinder 100 is connected to a feeding mechanism 300.

[0038] The excitation coil 200 is used to generate a pulsating magnetic field to amplify the difference in force between the magnetic particles and the non-magnetic impurities in the ore material. The magnetic particles are pulled downward by the magnetic field and move downward into the concentrate area at the bottom of the conical concentrator 1004 .

[0039] Preferably, multiple groups of excitation coils are installed between the inner cylinder 100 and the outer cylinder 1001, and the coils are powered on and off according to a certain pattern to generate a pulsating magnetic field in a downward direction.

[0040] The pulsating mechanism 400 can change the flow state of the slurry in the inner tube 100 and the overflow liquid level, so that the slurry pulsates and the slurry surface produces a surge effect, and generates a pulsating slurry flow through periodic reciprocating motion. The pulsating slurry flow forms a vertical alternating slurry flow force in the jigging magnetic flotation column, so that the mineral particles entering the inner tube 100 and the conical concentrator 1004 can be re-stratified under the action of the vertical alternating medium flow and the pulsating magnetic field.

[0041] Preferably, the excitation magnetic field and the pulsating slurry flow pulsate in opposite directions synchronously under computer control, realizing the pulsating flotation and washing magnetic separation functions, saving water resources. Specifically, when the pulsating mechanism 400 pulsates to raise the slurry level, the magnetic field strength generated by the excitation coil 200 is increased synchronously, and conversely, when the pulsating mechanism 400 pulsates to lower the slurry level, the magnetic field strength generated by the excitation coil 200 is reduced synchronously.

[0042] The feeding mechanism 300 is used to convey mineral materials to the inner tube 100 .

[0043] The conical concentrator 1004 is used to concentrate and precipitate magnetic ore. Under the action of magnetic field force and gravity, the hydrophilic particles overcome the buoyancy and the impulse of pulsating fluid and enter the conical concentrator 1004 at the bottom. After precipitation and concentration, they can be discharged as concentrate. The conical concentrator 1004 is connected to the inner cylinder 100 by a support flange, and the diameter of the middle hole of the support flange is the same as that of the inner cylinder 100.

[0044] Preferably, the cone angle of the conical concentrator 1004 is between 15 degrees and 135 degrees.

[0045] The advantage of this embodiment is that, under the action of the excitation coil 200 and the pulsation mechanism 400, the difference in force between the magnetic particles and the non-magnetic impurities in the ore is amplified, and the magnetic particles are pulled downward by the downward magnetic field to enter the bottom concentrate area of ​​the conical concentrator 1004, while the non-magnetic or weakly magnetic impurities are not or are less affected by the downward magnetic force, and are accelerated to move upward under the action of the buoyancy increased by the upward pulsation flow velocity, float into the top and overflow, and the ore is stratified within the inner cylinder 100 and the conical concentrator 1004. The pulsation of the ore pulp increases the momentum of the solid ore particles, and the movement of the magnetic ore particles therein to cut the magnetic lines of force also enhances the separation effect of the magnetic field on the magnetic minerals and non-magnetic minerals, replacing the washing effect of the washing water. The use of the jig pulsation technology instead of the washing water to provide power for the impurities to float up solves the technical problem that the washing magnetic separator needs to use a large amount of washing water and the addition of water to the flotation column affects the concentration of the reagent, making it possible to apply the magnetic flotation composite beneficiation method to magnetite. The strength of the separation magnetic field is adjusted synchronously and reversely, which solves the problem of "black" overflow tailings and magnetic inclusions in magnetic concentrate caused by jig pulsation. It not only prevents the occurrence of "slurry running out of the trough and ore bubbling" accidents in flotation machines and "black bubbling" accidents in washing magnetic separators, but also improves product recovery and concentrate indicators. Slurry pulsation can also prevent non-selective flocculation of fine-grained minerals, thereby improving the grade of iron concentrate and separation efficiency. The present invention can be used alone as a washing magnetic separator or flotation column, or as a composite magnetic flotation column, especially in water-scarce areas, which can greatly reduce water and electricity consumption and the volume of tailings, save equipment investment costs, and reduce equipment site occupancy.

[0046] Embodiment 2:

[0047] See also Figures 1 to 3 , Figure 6 On the basis of Example 1, it is further obtained that the outer cylinder 1001 is fixedly connected to the outer periphery of the inner cylinder 100, the top of the inner cylinder 100 is fixedly connected to an inverted cone 1002, the top of the inverted cone 1002 is fixedly connected to an overflow weir 1003, the outer periphery of the overflow weir 1003 is fixedly connected to an overflow trough 700, and an overflow port 7001 is opened on one side of the overflow trough 700.

[0048] The inverted cone 1002, the overflow weir 1003, the overflow trough 700 and the overflow port 7001 are used in conjunction with each other so that the mineral materials that overflow the overflow weir 1003 in excess can be collected and recycled.

[0049] Optionally, the inverted cone 1002 is a cavity structure whose cross section gradually expands from bottom to top.

[0050] Optionally, the inverted frustum 1002 is a uniform cross-sectional structure.

[0051] Optionally, the inverted frustum 1002 is a combination of a structure with a uniform cross-section and a structure with a cross-section that gradually expands from bottom to top.

[0052] The advantage of this embodiment is that under the action of the excitation coil 200 and the pulsation mechanism 400, the difference in force between the magnetic particles and the non-magnetic impurities in the ore is amplified, and the magnetic particles are pulled downward by the downward magnetic field into the concentrate area at the bottom of the conical concentrator 1004, while non-magnetic or weakly magnetic impurities are not affected or are less affected by the downward magnetic force. When the pulsating chamber 4001 is pushed forward, the slurry in the inner tube 100 is squeezed, and under the action of the buoyancy increased by the increase in the upward flow velocity, the mineral particles accelerate to move upward, and the slurry level in the overflow weir 1003 becomes higher, which is more conducive to the impurities quickly crossing the overflow weir 1003 and finally overflowing to become tailings. On the contrary, when the pulsating chamber 4001 is pulled, the upward flow velocity of the slurry decreases, which is conducive to the rapid sedimentation of the magnetic particles brought to the overflow area and returning to the lower magnetic separation area of ​​the inner tube 100. The slurry level of the overflow weir 1003 is lowered, and it is not easy for high-density magnetite to cross the overflow weir 1003 and enter the tailings, and the magnetic field strength is simultaneously reduced, which is conducive to the impurities mixed and wrapped by the magnetic agglomeration of the concentrate to be released into the upper overflow area.

[0053] In addition, the inverted truncated cone 1002 is designed as a cavity with a gradually increasing cross-sectional area from bottom to top, which increases the radial movement distance of the overflow ore particles and reduces the overflow speed in the variable diameter area. The magnetic particles washed to the overflow surface are prone to sedimentation due to their high density and small volume, and cannot cross the overflow weir and enter the tailings. However, general mineralized bubbles and impurities are basically not affected due to their low density and large volume. The overflow of useful minerals is avoided, which affects the recovery rate.

[0054] Preferably, a jigging controller 800 is fixedly connected to one side of the pulsating mechanism 400 .

[0055] The jigging controller 800 is used to control the movement mode of the pulsation mechanism 400. Under the control of the jigging controller 800, the pulsation mechanism 400 reciprocates at a certain frequency and amplitude, causing the slurry flow inside the inner tube 100 to pulsate and causing the slurry liquid surface in the inner tube 100 to produce a surge effect.

[0056] Preferably, the action produced by the pulsation mechanism 400 is controlled to be synchronized with the action produced by the excitation coil 200. Specifically, when the pulsation mechanism 400 pulsates to raise the slurry level, the magnetic field strength produced by the excitation coil 200 is increased synchronously, and conversely, when the pulsation mechanism 400 pulsates to lower the slurry level, the magnetic field strength produced by the excitation coil 200 is reduced synchronously.

[0057] Alternatively, if Figure 2 As shown, the inner cylinder 100 is provided with a bulk material barrel 1006, one side of which is connected to the conveying pipe 3006 of the feeding mechanism 300, the top of the bulk material barrel 1006 is not lower than the overflow trough 700 or the overflow weir 1003, and the bulk material barrel 1006 is installed through the overflow trough 700 and the inner side of the overflow weir 1003.

[0058] Preferably, a bulk material distributor 3003 is connected to the bottom of the bulk material distributor cylinder 1006 . The bulk material distributor 3003 is a conical structure and is placed inside the inner cylinder 100 and is higher than the top of the conical concentrator 1004 .

[0059] The bulker 3003 allows the mixed mineral material to be evenly scattered inside the inner cylinder 100 through the bulker cylinder 1006 and the bulker 3003 .

[0060] Alternatively, if Figure 3 As shown, a bulker 3003 is provided at the upper part of the inner cylinder 100, and the top of the bulker 3003 is connected to the conveying pipe 3006 of the feeding mechanism 300; the bulker 3003 is higher than the top of the conical concentrator 1004 and lower than the inverted truncated table 1002. The bulker 3003 allows the stirred mineral material to be evenly sprinkled inside the inner cylinder 100 through the conveying pipe 3006 and the bulker 3003.

[0061] In this example, if Figure 6 As shown, the bulk material distributor 3003 includes: a distribution chamber 30032 at the center, the top of the distribution chamber 30032 is connected to the conveying pipe 3006, and the outer periphery of the distribution chamber 30032 is symmetrically fixedly connected to a plurality of bulk material pipes 30031; the bulk material pipe 30031 is horizontally provided with a bulk material opening 30033 guided by a guide plate 30034.

[0062] Preferably, a balancing column 1008 is coaxially fixedly disposed between the bottom of the bulk container 3003 and the conical concentrator 1004 .

[0063] The balance column 1008 is used to stabilize the slurry flow field and overcome the magnetic field blind area.

[0064] Preferably, a concentrate regulating valve 1005 is fixedly connected to the bottom of the conical concentrator 1004 .

[0065] The concentrate regulating valve 1005 is used to discharge the concentrate from the bottom concentrate area of ​​the conical concentrator 1004 or to control the concentration of the underflow slurry.

[0067] Embodiment three:

[0068] See also Figures 1 to 5 , and on the basis of the first embodiment, the feeding mechanism 300 further comprises:

[0069] The mineralizer 600 is used to mix the flotation reagent in the ore to modify the surface of the ore particles;

[0070] The stirring mechanism 900 is inserted and fixedly connected to the center of the top of the mineralizer 600;

[0071] A feed pipe 3001 is fixedly connected to one side of the top of the mineralizer 600 and is used to add mineral materials;

[0078] The particles in the ore pulp are divided into magnetic / strong magnetic minerals and non-magnetic / weak magnetic gangue minerals according to the strength of magnetism, and are divided into hydrophobic minerals and hydrophilic minerals according to the flotation operation. Adding flotation reagents to the ore slurry can modify the surface of some particles. For example, the surface of non-magnetic / weak magnetic gangue minerals or other impurities can be converted into hydrophobic minerals after hydrophobic treatment, so that they will reunite and adhere to microbubbles for the first time in the shortest possible time, initially forming "flocs" and moving upward. Magnetic / strong magnetic minerals, as hydrophilic minerals, will not reunite or adhere to microbubbles, and will settle downward under the action of gravity, realizing the separation of hydrophobic minerals and hydrophilic minerals. With the help of flotation reagents and bubbles, different minerals can be separated, and mineral separation can be achieved regardless of whether the minerals are magnetic or not. For example, magnetite can be selected, as well as non-metallic ores and non-magnetic metal ores, such as copper and gold.

[0082] Preferably, a circular groove corresponding to the movement trajectory of the support member 9009 is opened at the top of the support frame 9005, and the support member 9009 is slidably connected to the inside of the circular groove. Through the opened circular groove, the support member 9009 can rotate inside the support frame 9005. The set support member 9009 can support the worm gear 90095, making the worm gear 90095 more stable during the rotation process.

[0083] Preferably, a circular hole corresponding to the position of the rotating shaft 9006 is opened inside the load-bearing frame 9008 and the mineralizer 600, and the rotating shaft 9006 is slidably connected to the inner side of the circular hole.

[0084] The advantage of this embodiment is that when in use, the material is added to the inside of the mineralizer 600 through the feeding pipe 3001 and the doser 3004. When the mineral material inside the mineralizer 600 needs to be stirred, the stirring motor 9002 is turned on, so that the stirring motor 9002 drives the stirring plate 9001 to rotate through the rotating shaft 9006, so that the stirring plate 9001 can stir the mineral material inside the mineralizer 600. When the stirring position of the stirring plate 9001 needs to be adjusted, the worm 90093 is driven to rotate by the driving motor 90092, so that the worm 90093 drives the threaded rod 90095 through the worm gear 90095. 9004 rotates, so that the threaded rod 9004 drives the lifting plate 9003 and the load-bearing frame 9008 to move upward, so that the load-bearing frame 9008 can drive the stirring motor 9002 to move upward, so that the stirring motor 9002 can drive the stirring plate 9001 to move upward through the rotating shaft 9006, so that the stirring height of the stirring plate 9001 can be adjusted, so that the device can stir the mineral materials at different heights inside the mineralizer 600, and the stirring helps to mix the ore and the chemicals evenly inside the mineralizer 600.

[0086] Embodiment five:

[0087] See also Figures 1 to 3 , and on the basis of the second embodiment, the pulsation mechanism 400 further comprises:

[0088] A pulsating chamber 4001, one side of the pulsating chamber 4001 is fixedly and tightly connected to the side wall of the conical concentrator 1004, the other side of the pulsating chamber 4001 is fixedly and tightly connected to a pulsating rubber disc 4002, the outer side of the pulsating rubber disc 4002 is connected to a connecting rod 4004, the other side of the connecting rod 4004 is fixedly connected to a driver 4005, a pulsating disc 4003 is provided on the driver 4005, and the driver 4005 is connected to the jigging controller 800 by electrical signals.

[0089] The pulsating rubber disc 4002 and the driver 4005 can be a tympanic membrane / diaphragm + cylinder made of elastic material, or a piston system + cylinder system.

[0090] Preferably, the driver 4005 is connected to the jig controller 800 via an electrical signal, and the jig controller 800 is used to drive the pulsating disk 4003 to perform periodic reciprocating motion, so that the pulsating rubber disk 4002 generates periodic pulp flow inside the inner cylinder 100 .

[0091] The advantage of this embodiment is that the pulsating disk 4003, the connecting rod 4004, the driver 4005, the pulsating rubber disk 4002, and the pulsating chamber 4001 are used in combination to generate a pulsating slurry flow through periodic reciprocating motion. The pulsating slurry flow forms a vertical alternating slurry flow force in the inner cylinder, so that the mineral particles entering the conical concentrator 1004 can be re-stratified under the action of the vertical alternating medium flow.

[0092] Embodiment six:

[0093] See also Figures 1 to 3 On the basis of Example 1, a microbubble generating mechanism 500 is further provided at the bottom and the outer side of the conical concentrator 1004 .

[0094] The microbubble generating mechanism 500 is used to disperse and crush air into a large number of microbubbles. The diameter of these bubbles is usually very small, which can provide sufficient flotation interface and is conducive to the adsorption and separation of hydrophobic mineral particles.

[0095] Preferably, the microbubble generating mechanism 500 includes a microbubble generator 5001, one side of the microbubble generator 5001 is fixedly connected to the inside of the conical concentrator 1004, the other side of the microbubble generator 5001 is fixedly connected to the outside of the conical concentrator 1004 and is fixedly connected to a gas separation tube 5004, one side of the gas separation tube 5004 is fixedly connected to a servo valve 5003, and one side of the servo valve 5003 is fixedly connected to a high-pressure gas source 5002. The microbubbles generated by the microbubble generator 5001 in the inner cylinder 100 are mixed and collided with the ore pulp and the reagent in reverse flow to form mineralized bubbles to complete the bubble mineralization process, and the mineralized bubbles adhere to the hydrophobic particles in the ore pulp and float to the overflow weir 1003 and enter the overflow tank 700.

[0096] Preferably, there are several microbubble generators 5001, which are respectively inserted and fixedly connected to the side wall of the conical concentrator 1004, and the air outlet holes penetrate into the inner cylinder 100, and the insertion depth can be adjusted. Through the provision of several microbubble generators 5001, the air is further dispersed and crushed into a large number of fine bubbles.

[0097] Preferably, the microbubble generator 5001 can be a venturi tube, an air gun, an aeration head, etc. The microbubble generator can be multiple or a combination of multiple. The microbubble generator 5001 is connected to the servo valve 5003, and the inflation amount is adjusted by changing the air intake or the number of branches used.

[0098] Open the high-pressure gas source 5002 and the servo valve 5003, so that the servo valve 5003 can inhale external air and transfer it to the inside of the gas separation tube 5004, and transmit the gas to the inside of the microbubble generator 5001 through the gas separation tube 5004. Since the gas separation tube 5004 provides a stable gas supply for the microbubble generator 5001, the microbubble generator 5001 can continuously and efficiently generate a large number of fine bubbles, ensuring that this embodiment can process more ore particles and improve the processing capacity of the equipment.

[0099] The microbubble generating mechanism 500 works together with the excitation coil 200 and the pulsation mechanism 400. When the waves rise, more impurity ore particles or mineralized bubbles attached to the impurity ore particles accumulated in the overflow area can be poured out and enter the overflow tank to become tailings. The excitation coil 200 synchronously enhances the magnetic field to suppress the outflow of magnetite. Similarly, when the waves are low, impurity ore particles or mineralized bubbles attached to impurity ore particles and magnetic ore particles are not easy to overflow. Taking advantage of this opportunity, the magnetic field is weakened, which is conducive to the dispersion of magnetic agglomerates, and the impurity particles mixed and wrapped by strong magnetic particles are detached by the way, and the bubbles are re-adhered to the upward direction and enter the tailings. Prevent impurities from being wrapped into the bottom concentrate area.

[0100] After the flotation reagent and the raw ore pulp are mixed and fed into the feeder by the feeding mechanism 300, they enter the inner cylinder 100 and disperse. The microbubble generating mechanism 500 generates bubbles in the inner cylinder 100, and the bubbles collide and adhere with the hydrophobic particles in the sinking ore pulp, and float up under the action of buoyancy and pulsating fluid impulse, overcoming gravity. The internal ore pulp flow pulsation and the surge effect of the liquid surface are superimposed, and the mineralized bubbles adhering to the hydrophobic particles and the hydrophobic particles enriched below the liquid surface that fall off from the mineralized bubbles and other non-(weakly) magnetic hydrophilic impurities in the ore pulp pass over the overflow weir 1003 at the top of the inner cylinder 100 and enter the overflow tank 700, and are discharged through the overflow port 7001. Under the action of magnetic field force and gravity, the hydrophilic particles overcome the buoyancy and pulsating fluid impulse and enter the bottom conical concentrator 1004 downward, and after precipitation and concentration, they are discharged through the concentrate regulating valve 1005 to become concentrate. Adjusting the magnetic field and the pulsation frequency and amplitude of the ore pulp is beneficial to improving the sorting effect, so that relatively high-density magnetic particles cannot overflow over the overflow weir 1003.

[0101] In actual operation, the above scheme has outstanding comprehensive technical effects: under the condition that the pulsating slurry flow and the pulsating magnetic field are synchronized but the forces are opposite, the difference in force between the magnetic particles and the non-magnetic impurities is amplified, and the pulsating chamber 4001 is pushed forward during operation, the slurry is squeezed and the upward flow velocity increases. Synchronously, the magnetic field strength becomes stronger, and the magnetic particles are pulled by the downward magnetic field more, which offsets the buoyancy increased by the increase in the upward flow velocity. Under the downward combined force of gravity, magnetism, etc., the particles continue to descend into the bottom concentrate area and are discharged through the concentrate regulating valve 1005. Non-magnetic or weakly magnetic impurities + bubbles are not affected or are less affected by the downward magnetic force, and are accelerated to the top under the action of the buoyancy increased by the increase in the upward flow velocity. When the impurities move upward, more impurities enter the overflow tank 700 when the slurry level rises under the action of the jig pulsation and the action of bubbles. At this time, the slurry level in the overflow tank 700 area becomes higher, which is more conducive to the impurities quickly crossing the overflow weir 1003 and finally overflowing to become tailings. On the contrary, when the pulsation chamber 4001 is pulled, the upward flow rate of the slurry decreases, which is conducive to the rapid sedimentation of the magnetic particles brought to the overflow area and returning to the lower magnetic separation area of ​​the inner cylinder 100. The slurry level in the overflow tank 700 area decreases, and the high-density magnetite is not easy to cross the overflow weir 1003 and enter the tailings, which simultaneously reduces the magnetic field strength, which is conducive to the impurities mixed and wrapped by the concentrate magnetic agglomeration to be released into the upper overflow area. In addition, the inverted truncated cone 1002 is designed as a cavity with a gradually enlarged cross-sectional area from bottom to top, which increases the radial movement distance of the overflow ore particles and reduces the overflow speed in the variable diameter area. The magnetic particles washed to the overflow surface are prone to sedimentation due to their high density and small volume, and cannot cross the overflow weir into the tailings. However, general mineralized bubbles and impurities are basically not affected due to their low density and large volume. This avoids the overflow of useful minerals and affects the recovery rate.

[0102] The present invention does not require a foam tank and a foam scraping device, does not require a certain thickness of foam layer and a stable gas-liquid cross section, and allows tailings slurry + bubbles to overflow directly. By automatically controlling the synchronous reverse pulsation process of the excitation magnetic field and the pulsating airflow, the problem of "slurry running out of the tank and ore" in the existing flotation machine and "black ore running out of the washing magnetic separator" is solved, and the product recovery rate is improved.
