A study has been carried out on the use of solvent extraction toremove copper from concentrated zinc sulfate leach solution. Ina series of experiments using a plant leach solution containing2 g/1 Cu, 2 G/1 Fe, 173 g/1 Zn, 7.9 g/1 H2SO4, 250 mg/1 Co andLIX 622 in SX-1, up to 97-98% of the copper present in the zincsulfate leach solution was extracted with negligible co-extractionof zinc, iron, cadmium and cobalt. The selectivity of copper overother metals in solution was very high. Copper was extractedselectively from solution at relatively low pH modification. Thecopper-loaded organic was almost completely stripped using 150 g/1sulfuric acid solution.
