Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.

Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc. Sometimes it will also use weak magnetic separation or strong magnetic separa
