Advances in solvent extraction for copper by optimized

Abstract. Solvent extraction for copper was first achieved commercially by use of weak ketoxime reagents which exhibited many limitations in terms of strength, selectivity, phase disengagement and in some cases stability. The more recently developed salicylaldoximes are very strong and highly selective, and they possess very rapid kinetics.
