Development and Evaluation of Ion-Exchange Silver Recovery Pilot Plant
Abstract
An ion-exchange silver recovery pilot plant was designed, constructed, and operated to determine the feasibility of using ion-exchange resins to recover silver from spent photographic fixer solutions. Results indicate that ion-exchange silver recovery is technically feasible since the silver concentration in the fix tank can be maintained below 0.05 gm Ag(+)/l with complete recycle of the fixer solution, the ion-exchange resin can be regenerated, and the silver can be recovered from the regenerant solution by electrolysis. Cost evaluation of the ion-exchange silver recovery system indicates that this method is not the most economical for recovering silver from fixer solutions; electrolytic recycling appears to be more economical.
