The process of chromite ore mining can be divided into 2 areas: 1. Feed preparation. 2. Concentration. The feed preparation stage involves the introduction of various physical separation equipment including crushers, screens, and grinding mills. The principal function of this stage is size reduction in preparation for the concentration phase.

Chromite Beneficiation Process

Apr 12, 2016  Chromite Process Summary This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.
