ABSTRACT:
After the non-cobalt values are stripped from the co-loaded organic, the cobalt ions on the organic are reduced to the divalent state. The organic loaded with divalent cobalt ions is easily stripped with a dilute acid to render the organic recyclable.
In another embodiment of the invention simultaneous reduction and "crowding" is utilized to strip cobalt from the organic. In this embodiment, a convenient source of both reductant Cu.sup.+ and of copper and/or nickel such as pregnant leach liquor is used to crowd the reduced cobalt from the organic.
