Chromium, For the production of pure chromium, the iron must be separated from the chromium in a two step roasting and leaching process The chromite ore is heated with a mixture of calcium carbonate and sodium carbonate in the presence of air The chromium is oxidized to the hexavalent form, while the iron forms the stable Fe 2 O 3
