Apr 04 2000 · Abstract A process for recovering gold from thiosulfate leach solutions and slurries in which gold is loaded into an ion exchange resin. Gold is recovered from the resin by elution with polythionate ions and the resin is regenerated with sulfide or sulfite. Gold is recovered from the eluate by precipitation with sulfide ions cementation or electrowinning.
