Metal recovery apparatus (20) being a diaphragm-less electrolytic cell arrangement where oxidizing reactions are achieved in a cathode cell (32) in an anode mode and reducing reactions in the anode cell (43) in a cathode mode by changing the direction of current flow. Better performance is achieved by pulsing (27b) the DC power (27b) to the electrodes and in some applications, installing plastic mesh (165) over the surface of the solution electrodes (24, 31) to reduce unwanted side reaction.
