Specifically, the driving member 21 is a driving motor, and is disposed at the top of the separation column 1, and the position and shape of the stirring impeller 22 can be adaptively adjusted according to the requirement, and the rotation speed thereof is controllable.
In this embodiment, the bottom of the inner cavity of the separation column 1 is provided with the water distribution member 3, the water distribution member 3 is fixedly arranged below the stirring impeller 22, the bottom of the separation column 1 is provided with the underflow port 12, the water distribution member 3 is funnel-shaped, the opening end of the water distribution member 3 faces the stirring impeller 22, the contraction end of the water distribution member 3 is communicated with the underflow port 12, and the side wall of the water distribution member 3 is provided with water distribution holes.

The magnetic pulse counter-current sorting device of the embodiment works as follows:
the driving motor is started to enable the stirring impeller 22 to obtain a certain rotating speed, the external water pump is started, and then the pulsating device 5 is started to enable the ascending water to penetrate through the water distribution piece 3 to continuously provide pulsating ascending water for the separation bed layer. The external current controller is activated to provide a varying magnetic field within the sorting cylinder 1. Ore pulp enters a separation chamber along a feeding hole 13, under the action of ascending water flow, a magnetic field and stirring, a separation bed layer keeps a certain loose degree, and particles with larger magnetic force and larger density continuously descend because the magnetic force and gravity applied to the particles are larger than the vector sum of self buoyancy and water drag force applied to the particles, finally descend to a settling zone and are discharged from a underflow port 12; the less magnetic and less dense particles continue to rise due to less magnetic and gravitational forces than the vector sum of their own buoyancy and fluid drag. The floating material enters the inclined sorting column 6 for sedimentation and sorting, the particles with larger density sedimentate to the inclined plate 61 and return to the inner cavity of the sorting column 1, and the particles with smaller density enter the overflow groove 62 under the action of the drag force of the fluid and are discharged from the overflow port 63 of the overflow groove.
Therefore, in the field of metal ore separation, the gangue minerals are mostly quartz, and the density and specific magnetization coefficient of the metal mineral particles are relatively large. Because of the poor, fine and impurity problems of the existing minerals, the dissociation particle size is extremely fine, the fine particle size and the materials with density and magnetic difference enter a separation region, the particles with high density and higher specific magnetization coefficient sink to the bottom under the combined action of magnetic force and gravity, the pulsating water flow provided by the pulsating device 5 makes the particles with higher density more prone to sink to the lower side of the particle group with lower density, and the loose action provided by the stirring device 2 further reduces the entrainment of the particles with low density and low specific magnetization coefficient in the underflow. The metal particles with smaller particle size are still possibly brought into the upper layer of the fluidized bed by the ore pulp due to insufficient gravity and magnetic force borne by the metal particles, so that the metal particles enter the area of the inclined plane separation column 6, when the ore pulp flows through the gap of the inclined plate 61, the flow velocity is in gradient distribution, and the flow velocity is smaller when the ore pulp is closer to the inclined plate 61, so that the fluid drag force borne by the low-density and large-particle-size particles deposited on the inclined plate 61 is far larger than that of the high-density and small-particle-size particles, finally, the low-density and large-particle-size particles are discharged through the overflow groove 62 along with ascending water flow, the high-density and small-particle-size particles fall back into. Thereby improving the treatment capacity, reducing the tail leakage of heavy particles in overflow, improving the recovery rate and the separation efficiency, and being widely used for the desliming, grading, pre-discarding tail and purifying operation of coarse and fine minerals.
Specifically, when the magnetic pulsating countercurrent sorting apparatus of the present embodiment is used to separate a complex mixed system of broad-size magnetite and quartz particles, all the particles in the sorting cylinder 1 of the present embodiment are subjected to gravity to settle down, and tend to be discharged from the underflow. The magnetite particles of high density always settle on the bottom layer more preferentially due to the difference in the interfering settling velocity of the particles of different densities, and also due to this settling action, the particles will accumulate in an extremely high concentration on the upper portion of the underflow port, thereby losing the separation effect of sorting, the high velocity flow of the fluid brought about by the rotation of the stirring impeller 22 will re-disperse this portion of accumulated particles, and the drag force caused by the rising water pulls the low density nonmagnetic quartz particles upward. The sinusoidal pulsating water flow caused by the rapid advance or rapid retreat of the slurry flow in the column body by the pulsating device 5 is more beneficial to the layering among the light and heavy particles, which is similar to the jigging principle. But at the same time, the magnetite particles with higher density are thrown into the upper layer by the high-speed water flow caused by stirring and pulsation, and part of the magnetite particles with high density of fine-grained level are carried away by the ascending water, so that the metal minerals are lost in the tailings. However, the introduction of the magnetic field causes the part of the magnetic high-density magnetite particles thrown into the upper layer to continuously receive a larger downward magnetic force, and the fine magnetic particles are mutually aggregated into particles with larger particle size due to the magnetic linkage, so that the particles are easier to settle, and are prevented from being brought into tailings by the drag force of the fluid. In mineral sorting, particularly physical sorting, one hundred percent of heavy particles cannot enter heavy products, which is the mismatching rate, and the inclined sorting column 6 at the upper part of the sorting column 1 is used for reducing the loss of the heavy minerals. The inclined narrow channel in the inclined sorting column 6 leads to the magnetite particles with higher density to be deposited on the inclined plate 61 more quickly, and the quartz is easier to be accumulated on the upper side of the deposition layer far away from the inclined plate 61 due to the slower settling speed, the fluid speed of the area where the heavy particles closer to the inclined plate 61 are located is smaller and close to zero, the magnetite particles with higher density flow back into the sorting column 1 under the action of gravity, and the upper-layer quartz particles with lower density are gradually substituted into the overflow groove 62 under the action of the drag force of upward pulsating water flow and then are discharged into tailings. Therefore, the grade and the recovery rate of the heavy particles can be greatly improved under the synergistic cooperation of magnetic force, a fluidized bed, pulsation, stirring and inclined surface separation.

Those skilled in the art can make numerous possible variations and modifications to the present invention, or modify equivalent embodiments to equivalent variations, without departing from the scope of the invention, using the teachings disclosed above.
