ABSTRACT:
A process for recovery of metal values from a mixed metal chloride containing leach solution by contacting the leach solution with a water immiscible solution of a complexing agent selective for the neutral chloride of the metal to be recovered and a chelating agent having affinity for the cation of the metal to be recovered. The chloride ion is washed from the water immiscible solution by contact with a chloride ion washing solution. The water immiscible solution containing the chelated metal ion is stripped with an aqueous stripping solution. The metal is recovered from the aqueous stripping solution.
