copper to anodes (>99% Cu) removes dissolved gases and some metallic impurities. The aim of final electrolytic refining is to produce cathodes with a maximum of 65 ppm metallic impurities. The main process stages to recover valuable elements and remove excess impurities are anode slime treatment and electrolyte purification.

In the actual copper-refining operation, the impure alloy of copper, nickel, gold, etc., is cast in a thin, flat plate constituting the anode: the cathode is usually a sheet of pure electrolytic copper. Anodes and cathodes (30 to 40 of each) are immersed in a cell containing copper sulphate and sulphuric acid which serves as an electrolyte. The action of the electric current can be easily ...

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 Electrorefining is a much more common process than ...
