mines are already exploiting other chromite layers within the Middle group, and these are the MG2, 3 and 4 [6]. This might be due to depreciation of high-grade chromite seams. Chromite processing involves crushing, milling to less than 1mm and further beneficiation using gravity circuits and spiral concentrators are widely used for this purpose.
