Abstract: The feasibility of in-situ precipitation as the regeneration step in ion exchange for silver recovery is presented. In this step, the silver is precipitated inside the resin instead of eluted with a regenerant. The resin can be reused for many cycles with no decrease in capacity, and the accumulated silver can then be recovered by incinerating the resin. This procedure, like conventional ion exchange, is effective only for effluents containing low thiosulfate concentrations. Effluent silver levels below those of conventional ion-exchange methods have been achieved in our experiments, with the advantage of less supervision and better regeneration control.
