Electrolytic Refining Meaning Electrorefining Of Copper

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 ...
