Influence of Important Factors on Ammonia Leaching of Alkaline Zinc Oxide Mineral

Abstract:

The effects of refractory zinc oxide ore which came from Lanping of Yunnan Province were studied using agitation leach method in laboratory in order to find out the optimum leaching conditions. The optimum conditions obtained are as follows: ammonia concentration 3mol/L, ammonium bicarbonate 1.5mol/L, granularity (-0.074mm) about 85%, solid to liquid ratio 4:1, and leaching time 2h. On this condition, the test obtained the better index of the zinc leaching rate 74.4%.
