ABSTRACT:
A process is described for the recovery of copper values from an acidic aqueous solution containing copper values by means of liquid-liquid extraction, wherein the extractant is a mixture comprising a substantially water-immiscible organic solvent, one or more hydroxyoximes capable of extracting copper values, and one or more alpha, betadioximes of the anti-configuration. Novel alpha, beta-dioxime compounds are also disclosed.
