ABSTRACT:
A method and apparatus for reducing electrowinnable metal ion concentration to a low level in a process stream and recovering the metal electrolytically. Low concentration metal ions from the process stream are recovered in an ion exchanger and then recaptured from the ion exchanger into a relatively small volume of regeneration fluid. The regeneration fluid, pregnant with the metal ions, is electrolyzed in a particulate bed electrolytic cell to a relatively low level of metal ion concentration, and the regeneration fluid is then available for reuse in a further ion exchanger regeneration.
