Electro refining is the process used to refine copper metal.
A pure copper strip is used as a cathode whereas, block of crude metal is used as the anode and copper sulphate is used as the electrolyte.
When current is passed through the setup, the pure metal gets deposited on the cathode, thus, refining the impure block.
