WebbA copper anode is used to replenish the electrolyte with copper cations Cu2+ as they are plated out at the cathode. The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the … WebbThis resulted in plating of gold and silver and minimal plating of Cu. But the Cu needs to be removed from the circuit. A separate EW for the high Cu low Au & Ag solution would be used. But the use of a Zadra circuit instead of an AARL impacts the use.
