Polypropylene Gold Electrowinning Cell

Electrowinning is the process whereby metals, such as gold, are recovered from concentrated solutions by applying a voltage across electrodes immersed in the concentrated solution. The voltage applied across the electrodes (cathode and anode) results in a cathodic reaction which in turn results in the deposition of the metal from solution onto the cathode.The cathode is the electrode at which ...
