Electrolytic Refining Mining Fundamentals

Electrolytic Refining of Minerals References. Introduction. Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode.
