electrolytic refining process of copper in guinea

Electrolytic refining is 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 at the cathode In this setup an electrolyte metal salt aqueous solution depending on the metal is often used...
