  • Apparatus for the electrolytic recovery of silver from solutions containing silver
    Patent number: 5454924
    Abstract: An apparatus for the electrolytic recovery of silver from solutions containing silver is described. The apparatus comprises an electrolytic cell, an anode positioned within the cell, a reference electrode positioned within the cell, and a removable cathode positioned within the cell. The cathode has an inner face directed towards the anode and an outer face directed towards the reference electrode. The apparatus includes means for restraining the deposition of silver on the outer face of the cathode. The risk of incorrect potentials being sensed by the reference electrode are thereby reduced or avoided. The tendency for side reactions to occur is also reduced.
