Chromium Ore - an overview ScienceDirect Topics

In the alkaline process, the finely ground ore is roasted with Na 2 CO 3 under oxidizing conditions at 1100 °C. The sodium chromate is leached from the calcine. The solution is reduced with SO 2 and used for electrowinning, or Na 2 Cr 2 O 7 is crystallized then converted to Cr 2 O 3 for chromium production by aluminothermic reaction.
