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). The mine produced 452 000t of chromium in 2012. What chromium is used for?
