  • What is roasting of a sulfide ore?

    The concentrated ore ( received after crushing and floating) is roasted in a furnace in the presence of a current of air. Sulphur is oxidized to SO2 and impurities of arsenous and antimony are removed as volatile oxides. The following reaction takes place. 2CuFeS2 + O2 — Cu2S + 2FeS + SO2 S + O2 SO2 4As + 3O2 As2O3 4Sb + 3O2 2Sb2O3
