ABSTRACT:
A metal such as silver is recovered from an electrolyte by supply from a holding vessel to a plating cell at a replenishment rate which is automatically reduced when the electrolyte level in the vessel falls below a specified level. While the cell is fed at the reduced rate the cell is operated at a reduced current selected to equate the sum of dissolution from the electrode and metal introduction at the lower replenishment rate. Apparatus for carrying out the method is described.
