The vertical roller mills are also mainly gravity separators and magnetic separators. So at the beneficiation process, the equipment are quite different from each other because the chrome concentrating methods are different for different chrome ores. Many methods can be used in chrome ore beneficiation plants. 

The mainly chrome ore beneficiation method is gravity-separation. The mainly chrome ore concentrating equipment are ore washing box (called jigger), table concentrators, spiral chute, etc. . Usually, the chrome ore can be upgraded by jigging machines firstly, and then the shaking table can be used for secondary upgrading as fine selection to get final high grade chrome concentrate.The specific mineral beneficiation flow is as follows:

The raw ore should be crushed by jaw crusher initially. When it gets the reasonable fineness, it is transported into vibrating screen through conveyer and feeder.

The screened oresget the next procedure:milling process in ball mill, then nextjigging separation. The mill edore gets into chrome jig separator for gravity separation.
