During this process, part of the iron ore will accumulate on the upper surface of the quartz sand, resulting in the inability of the magnetic force to generate suction on the iron minerals, so that the iron minerals are moved out along with the quartz sand. For this reason, the utility model proposes a high-purity quartz sand magnetic separation device. Utility Model Content
