## A copper concentrate (CuFeS2 + FeS2 + gangue) of composition (wt%) Cu = 6%, S = 35% is roasted with (20+RN*)% excess air. Copper in the roasted product is as Cu2S and all the iron is converted to Fe2O3. Assuming that the gangue does not contain any Cu, Fe and S, Calculate for 1 ton of concentrate i) amount of minerals and gangue ii) volume of air supplied for roasting at STP. iii) Volume and composition of the evolved gas (flue) after roasting [atomic weight of Cu=64, Fe= 56, S=32, O=16, N=14]
