electrorefining of copper process

Electrorefining Chemistry Tutorial - AUS-e-TUTE

During the electrorefining stage of copper production, a series of impure copper anodes and thin starter sheet cathodes (such as thin copper foil) are suspended in a tank. The electrolyte containing the copper ions flows through tank. The electrolyte is often copper dissolved in sulfuric acid which produces an aqueous solution of copper ions.
