Chromite - Pasargad Neshan Pars

For the production of ferrochromium the chromite ore (FeCr2O4) is reduced with either aluminium or silicon in an aluminothermin 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.
