Chromite Mining Process 2 Processing Chromite Ore extracted from the mine with a grade of 40% chromium oxide or greater is suitable for processing directly in the offsite ferrochrome production facility. Ore with a lower grade must be processed to increase its chromite content. Ore that is not suitable to ship directly to the ferrochrome production

Chromium ore is processed and purified into chromium(III) oxide. This is reacted, very exothermically, in a Thermit style reaction, with aluminium (see reactions of aluminium) to free the chromium metal.
Chromium metal. Pure chromium is produced either by the thermal reduction of Cr2O3 with aluminum or by the electrolysis of trivalent chromium solutions. The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F).
