Abstract:
Processes for improving copper/iron selectivity in a solvent extraction circuit by contacting an acidic aqueous solution containing dissolved copper and iron ions with a solvent extraction composition including an orthohydroxyaryloxime, a selectivity modifier, and an equilibrium modifier, wherein the ratio of selectivity modifier to orthohydroxyaryloxime is from 0. 001 to 0. 05, thereby decreasing the copper:iron transfer ratio, are provided herein.
