Chromite is an iron chromium oxide (FeCr 2O4) mineral belonging to the spinel group [1]. The only ore of chromium is chromite ore which ferrochromium and metallic chromium are produced from it by extracting processes. South Africa is the largest producer of chromite ores, where over 70 % of world chromite ore reserves are believed to be located.

South African chromite ores and concentrates are blended to obtain a Cr/Fe ratio that is high enough to produce 'charge chrome', a special grade of high-carbon ferrochrome (HCFeCr). Charge chrome contains approximately 50-53% Cr, 6-8% C, 4-6% Si, and the balance Fe, with minor impurities such as S and P (Gasik, 2013).
