A circulating pump is connected to the circulating tank. A circulating tank drain pump is connected to the circulating tank. A recovery tank is connected to the circulating tank and the circulating pump. The recovery tank has an anode and a cathode positioned therein. A source of electric current is connected to the anode and the cathode. Metal is removed from the liquid by the method of circulating the liquid between the circulating tank and recovery tank.
