Jan 01, 2009 A hydrometallurgical treatment involving solvent extraction of zinc using di-2-ethylhexyl phosphoric acid D2EHPA has been investigated to recover zinc from an industrial leach residue. The residue was leached with sulfuric acid producing leach liquor which was subjected to solvent extraction for enrichment of zinc and removal of impurities.
Sep 10, 2003 The ore graded 15.2 Zn, 5.5 Fe, 4.9 Pb, and 14.4 S. Leachate from the pads was neutralized in three rubber-lined reactors. Then it was clarified and filtered, creating feed for the solvent extraction plant and a gypsumferric residue. From the 10,000 tonnes of agglomerated sulphide ore, 450 tonnes of zinc was recovered.
