| Abstract: | The Zinc concentrate was roasted for removal of sulphur, followed by the leaching of roasted concentrate with commercial - grade H2SO4 was performed. After removal of impurities via a series of procedures, the qualified zinc oxide product is prepared from leacheate by a hydrometallurgical extraction technology. The purity of product obtained reached 99.71%, and all kinds of technical indices conform to product standard,overall recovery of Zn element reached more 87%. |
