Environmental Code of Practice for base metals smelters and refineries
Electrorefining produces a purified metal from a less pure metal. This process is used to refine copper, nickel, and lead in Canada. The metal to be purified is cast as an anode and placed in an electrolytic cell. A current is applied, and the metal is dissolved into an acidic aqueous electrolyte or molten salt.
