name the process by which impure copper is purified

Electrolysis UW Madison Department of Chemistry

Because impurities can dramatically decrease the conductivity of copper wires, impure copper must be purified. One method of purifying copper is by electrolysis. When a strip of impure metallic copper is used as the anode in the electrolysis of an aqueous preparation of copper(II) sulfate, copper is oxidized.
