Chromite - Wikipedia


For the production of ferrochromium the chromite ore (FeCr 2 O 4) is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching process. Chromite is also used as a refractory material, because it has a high heat stability. The chromium extracted …

Chromium processing: Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
