Electrolytic refining refers to the technique of purifying metals, predominantly copper, through the procedure of electrolysis. Essentially, in this process, a chunk of impure metal is used as the anode, with a thin strip of pure metal serving as the cathode. The electrolyte is typically a metal salt aqueous solution, which varies based on the ...
