Electrolytic refiningis a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode, with a thin strip of pure metal as the cathode. In this setup, an electrolyte (metal salt aqueou…
