The Extraction of Copper - Chemistry LibreTexts
The copper(II) ions are removed again from the organic solvent by reaction with fresh sulfuric acid, producing a much more concentrated copper(II) sulfate solution than before. Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

2015-7-26 · Note: Until I added the questions in July 2015, I had always assumed (on no good evidence - never a good idea!) that chalcopyrite contained copper and iron both in the +2 oxidation state - but 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
