Zircon Mining Process Equipment Flow Cases - JXSC

Zircon is a non-magnetic mineral or a weakly magnetic mineral. Magnetic separation is divided into two types: dry type and wet type. Dry magnetic separation must be preheated before drying and grading. The wet magnetic separator has a wide particle size and a lower particle size of 20um. Therefore, when the zircon particle size is fine, the wet ...
