A Study on Leaching of Zinc Oxide Ore in Ammonium Sulfate Solution

Dan Dan Wu, Shu Ming Wen, Jing Yang, Yi Jie Wang, Chao Lv

Abstract

In this paper, the leaching effect of zinc oxide ore was investigated using ammonium sulfate solution as leaching agent. The effects of temperature, concentration of ammonium sulfate, average particle size and stirring speed on the leaching of zinc oxide ore were studied. The leaching rate increased with increasing solution temperature, concentration, and stirring speed as well as with decreasing average particle size. Ammonium sulfate solution can therefore be used as an effective leaching agent for zinc extraction from zinc oxide ore.
