For the production of ferrochromium the chromite ore FeCr 2 O 4 is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step roasting and leaching processMost zinc are produced at hydrometallurgically where a high grade zinc product can be obtained and valuable metals mixed in the raw material can be recovered In the hydrometallurgy the raw material of zinc concentrate is roasted and then dissolved in sulfuric acid to remove impuriti The process called leaching and pH control of the leachate is important
