extraction of copper mining, concentration, smeltingthe major steps in the extraction of copper are. copper in chalcopyrite is reduced to copper sulphide. just like in blast furnaces, calcium carbonate is added as a flux to create the slag. iron in chalcopyrite is removed as iron silicate slag. most of the sulphur in chalcopyrite turns into sulphur dioxide (so 2 ).
