Abstract
A method and apparatus for maintaining electro-deposition of metal on a cathode in an electrolytic cell. The cell comprises a metal anode, a cathode, an electrolytic bath and a main power supply to apply an electric potential across the anode and cathode resulting in a forward current and deposition of metal from said anode to the cathode. An auxiliary power supply is also provided for connection to the cell. In cases where the mains power supply falls below a predetermined value, the auxiliary power supply maintains a predetermined direction and quantity of current flow in the cell. The auxiliary power supply may be continuous or activated only when the current flow and/or direction of current falls below said predetermined value.
