[0003] However, the above-mentioned beneficiation method can only achieve one-time separation of coarse ore, and the grade of concentrate after magnetic separation is still low. If you want to continue to improve the grade of concentrate, you need to cooperate with other beneficiation equipment. more complicated

Abstract
The invention discloses a stirring magnetic separator and a magnetic separation process. The stirring magnetic separator comprises a cylinder body, an electromagnetic magnetic system, a stirring assembly, a first driving assembly and a second driving assembly, wherein the upper part of the cylinder body is provided with an inlet valve and the lower part is provided with an outlet valve; the electromagnetic magnetic system comprises a plurality of electromagnets which are arranged around the cylinder body, and two adjacent electromagnets in a circumferential direction have opposite polarities;the stirring assembly is arranged in the cylinder body; the first driving assembly is in transmission connection with the stirring assembly for driving the stirring assembly to rotate; and the seconddriving assembly is in transmission connection with the cylinder body for driving the cylinder body to rotate. The stirring magnetic separator provided in the invention can perform multiple times of separation on to-be-separated slurry, high-grade magnetic minerals can be obtained more conveniently, the structure of a mineral processing system is simplified, the area occupied by a mineral processing plant area is narrowed, and the mineral processing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of mineral processing, in particular to a stirring magnetic separator and a magnetic separation process. Background technique [0002] A traditional magnetic separator includes a cylinder, a fan-shaped magnetic system and a bottom box. The fan-shaped magnetic system is arranged in the cylinder and located at the lower end of the cylinder. When working, the ore slurry is fed from the lower part of the bottom box to the bottom of the rotating cylinder, and under the action of blowing water sprayed by the blowing water pipe, the ore slurry can be in a loose suspension state; among them, the magnetic ore particles are subjected to upward magnetic force and are released It is adsorbed on the outer wall of the cylinder and rotates with the cylinder. During the rotation, due to the alternating polarity of the magnetic poles, a magnetic flipping effect is generated, so that the gangue mixed in the magnetic group or ...
