- Abstract
Leaching test on the oxidized zinc ore from Kashi, Xinjiang Autonomous Region is studied in the (NH4)2SO4-NH3-H2O system; Systematic studies are made to show the effects of various factors on the leaching rate of zinc. The optimum conditions for leaching is finally confirmed, i.e., the grinding fineness is 80% -74um, concentration of ammonium sulfate is 2mol/L, concentration of ammonia is 4mol/L, reaction temperature is 40℃, the ratio of liquid to solid is 4:1; stirring rate is 300rpm and leaching time is 3h. Ultimately, the leaching rate of Zn could reach more than 91%.
