Anode potential-time curves have been determined for the selenide or telluride bearing copper anodes It was found that the potentials of these copper anodes were lower than that of electrolytic copper at the early stage of electrolysis. These differences of potentials increased as the temperature of the electrolyte was lowered and the current density was increased. As the electrolysis proceeds, the anode potentials raised for the sake of formation of anode slime. The composition of slime produced during electrolysis of the anode which contains copper selenide or telluride is different from that of original compound contained in anode.
