Electrorefining of Copper - UFRGS

2007-6-21  Electrorefining of Copper 1. Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, i.e. the electrode reactions are, at the anode: M → Mn+ + ne-and at the cathode: Mn+ + ne-→ M
