Wet magnetic separation is widely used in the purification of quartz sand, which has the characteristics of significant iron removal effect, large handling capacity and no dust pollution. In the primary stage of quartz sand purification, wet magnetic separation is generally considered to be an excellent way of iron removal purification, but in the stage of high-purity quartz cleaning, the conventional wet magnetic separation purification effect is not obvious, the reasons can be summarized as three points.
