Process Chromite Production

Chromium processing Britannica

Pure chromium is produced either by the thermal reduction of Cr 2 O 3 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).
