Electrowinning and Smelting Resource Book

The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).

In electro refining of copper, some gold is deposited as

In Electrolytic refining, the impure metal is made to act as an anode. A strip of the same metal in pure form is used as the cathode. They are put in a suitable electrolytic bath containing a soluble salt of the same metal. The more basic metal remains in the solution and the less basic ones go to the anode mud. Copper is refined using an electrolytic method.
