ABSTRACT:
The invention illustratively contemplates recovery of silver from waste photographic-fixer solution, the apparatus being so devised and controlled that high purity is achieved in the reclaimed metal without contamination of the remaining solution. As a result, the remaining solution may be recycled, and requirements for replenishment of fixer chemical are held to minimum quantities. In an automated employment of the invention, assurance is provided that electroplating action will be called for only when it can be safely performed, without impairment of quality in the reclaimed metal or in the recycled solution.
