It needs further refining. This is accomplished electrolytically by using an impure strip of copper as an anode. The electrolyte is an acidified aqueous solution of C u S O 4. For any cell - Galvanic or electrolytic - at the anode, oxidation happens. So the cathode is a strip of pure copper. C u 2 + (a q) gets reduced to pure metallic C u (s).
