Experimental Research on Leaching of Zinc,Indium and Germanium from Zinc Oxide Flue Dust by Mechanically Assisted Ball Milling AITranslate
Abstract AITranslate
In order to improve the leaching rate of zinc, indium and germanium in zinc oxide flue dust, a mechanically assisted ball milling and acid leaching process was proposed to treat zinc oxide flue dust.The effects of pellet-material ratio, end point acidity, reaction temperature, reaction time, stirring rate and oxidant on the leaching rate of zinc, indium and germanium were investigated.The results show that adopting the process of secondary acid leaching with mechanically assisted ball milling, the leaching rates of zinc, indium and germanium reach 93.35%,91.25% and 85.58%,respectively, under the conditions of liquid-solid ratio of 5∶1,ball-material ratio of 1∶3,reaction temperature of 85 ℃,reaction time of 2 h, end point aci-dity of 120 g/L,stirring rate of 800 r/min, and without oxidant.Compared with the original process, all the leaching rates are greatly improved, and the leaching effect is better.
