May 13, 2013 Chromite – Wikipedia, the free encyclopedia. For the chromium(III) anion and its salts, see Chromite (compound).… chromium; for those products the ore smelter process differs considerably. For the production of ferrochromium the chromite ore (FeCr2O4) is reduced with either aluminium … The concentrate is used to make ferrochromium, which is in turn used to make …Jul 01, 2010 An optimized process production of chromate by oxygen was proposed. The tests are executed by introducing NaNO 3 to the decomposition process of chromite ore in molten NaOH to decrease the decomposition temperature. An interesting result is that the reaction temperature could decrease from above 500 C to about 400 C, and sodium nitrate has no consumption in the oxidation process…
