ABSTRACT:
The process of the present invention for the recovery of metal ions from a polymeric chelating agent stream or solution comprises the circulation of a loaded polymeric chelating agent stream or solution through an electrolytic recovery cell. The chelating agent is loaded with metal ions or complexes of the species to be recovered which have been extracted from a feed stream or solution. These metal ions or complexes will be reduced and recovered from the chelating polymer by an electrodeposition method. If the chelating agent is used in a continuous flow-type system, the lean polymeric chelating agent can optionally be recycled for further use in extraction of the desired metal species. The addition of scrub and regeneration stages to such a system is optional, depending on feed stream composition.
