During the separation process, sometimes no magnetic field is provided and sometimes aggregate by charge magnetism and sometimes scatter away by demagnetization, whose order is from up to down and repeatedly circulating. The separated material is aggregated by charge magnetism and scattered by demagnetization in the post body for many times. The intersecting line of the magnetic separation post at the lower part is disconnected to supply water and produce a rising current. Under the function of the rising current's impulsive force, the gangue and adherent gangue are separated from the aggregate. As the separated material is scattered by demagnetization, the gangue is completely removed and the concentrate is high in quality but also the rising current amount can be reduced so as to save water flow and then to achieve the purpose of saving water.
