. The resulting metals are said to be electrowon. In electrowinning, a current is passed from an inert anode through a liquid leach solution containing the metal so that the metal is extracted as it's deposited in an electroplating process onto the cathode. In electrorefining, the anodes consist of unrefined impure metal, and as the current passes through the acidic electrolyte the anodes are corroded into the solution so that the electroplating process deposits refined pure metal onto the catho… (More on Electrowinning)
