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

The symbol and name for copper are from the Latin cuprum, which literally means "from the island of Cyprus", an early source of copper ore. Before 1982 U.S. pennies were pure copper. Now they are mostly zinc with a thin shell of copper. Most copper that is mined today is refined and drawn into wire for use in the electrical industries.
