does not occur in nature, it is present in chromite ores as an iron chromium oxide (FeCr2O4) (Gundewar et al, 2013). Different types of beneficiation techniques are using for chromite ores to remove gangue minerals from the chromite concentrations such as gravity separation, flotation or magnetic separation (Kroll-Rabotin et al, 2013).
The gravity separation process is the main beneficiation process used to recover chromite mineral. However, these conventional chromite processing techniques become …
of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to crushing, grinding, desliming and hydrosizing to produce a concentrate of about 50% Cr203 with a yield of about 25-35%.

Abstract– There are proven and well established widely accepted techniques for concentration of ...
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.
