Electrolytic Refining Mining Fundamentals

IntroductionElectrolytic Refining of MineralsReferencesElectrolysis, 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. Both the cathode and anode are dipped in an electrolytic cell containing an aqueous solution of the metal salt. Upon the application of electric current of a suitable voltage, pure metal is deposited at the cathode by the dissolutBuy Now
