copper extraction and purification

Note Until I added the questions in July 2015 I had always assumed on no good evidencenever a good idea that chalcopyrite contained copper and iron both in the 2 oxidation statebut that may well be wrong If it was true then you can show that the sulphide ions are reducing Cu II to Cu I However if the copper was in the 1 state originally then the sulphide ions are reducing
