摘要
陕西旬阳小河金矿的浮选金精矿含砷 (2 0 - 2 7% ) ,采用细菌预氧化时较为困难。采用不同方式对已有 T.f.菌进行驯化 ,有效地提高了细菌的氧化活性 ,金的浸出率从 0 .6 %提高到 85 .1 2 %。
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%).
