In this paper, a series of magnetic separation experiments and FEM-DEM simulations were carried to study the dynamic capture behavior of a dry magnetic separator (DMS) for biotite in fine aggregates. Experimental results show that the capture effect of a DMS on biotite in fine aggregates is greatly affected by the particle size.

The biotite obtained by magnetic separation were placed in a plastic screw bottle, in 4 to 5 centimeters of demineralized water. The bottle was then inserted into an ultrasonic tank filled with water, which was kept in operation for 1 hour. This manipulation made it possible to detach any minerals that might be attached to the biotite.

biotite magnetic separation. The nonmagnetic (weak) magnetic mineral mingled in the magnetic minerals is not or slightly affected by the adsorption of the magnetic force, moving to the outer layer gradually, and is thrown out by the centrifugal force, gravity and the joint action of magnetic turn and agitation of magnetic minerals.
