Abstract
Filter cakes obtained in the conventional acid leaching of zinc concentrate are
considered a major secondary source for zinc. Solvent extraction may be utilized for the
selective separation of zinc from other elements in hydrometallurgical processing of
such resources. In the present work, extraction of zinc from the solution obtained from
sulfuric acid leaching of cold purification filter cake of Angouran concentrate were
performed by using D2EHPA as the extractant. The effects of extractant concentration
diluted in Kerosene, solution pH and phase ratio (O:A) were investigated and their
optimized values were obtained to be 40 vol.%, 2.5-3 and 4:1, respectively. Under these
conditions, 98.8% of Zn could be extracted.
