ABSTRACT
Chalcopyrite concentrate from Hajar Mine, Morocco, was leached with nitro-fluosilicic acid leach solution. The pregnant leach solution obtained contained 19.3 g/dm3 Cu, 18.1 g/dm3 Fe, 4.5 g/dm3 Zn and 0.03 g/dm3 Pb. Copper recovery from this pregnant leach liquor was performed by solvent extraction using Acorga M5397 diluted in Escaid 110. McCabe–Thiele distribution isotherms showed that at pH 1.7 complete and selective copper extraction can be achieved with φo/φa =1.5/1 in 3 stages of extraction. Stripping of the loaded copper by treating the organic phases by a fresh sulphuric acid solution was easily realized.
