The important beneficiation process in the chrome processing plant mainly include comminution and concentration. 1. Comminution. Chrome lump ore, or chrome stone, must be crushed and ground into powder due to medium and fine dissemination grain sizes to liberate more chrome mineral. While chromite sand ore does not need the …

Magnesium frequently substitutes for iron in chromite. A solid solution series exists between the mineral chromite (FeCr 2 O 4) and the isomorphous mineral magnesiochromite (MgCr 2 O 4).Intermediate specimens can be rich in iron ((Fe,Mg)Cr 2 O 4) or magnesium ((Mg,Fe)Cr 2 O 4).For convenience in communication, these minerals …

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.
