| Abstract: | Because of the flotation gold concentrate (As-bearing 20%-27%) of Xiaohe gold deposit in Xunyang,Shaanxi,it is difficult to use bacterial preoxidize.By use different methods for T.f.bacterium undergone training,the activity of bacterial oxidation is added up extremly,the leaching of gold has been raised up to 85.12%(from0.6%). |
