采用两种嗜酸硫杆菌(嗜酸氧化亚铁硫杆菌和喜温硫杆菌)对铜蓝进行生物浸出,实验在有或没有4 g/L硫酸亚铁pH2.0、150转/分、35℃的三角瓶中进行.实验结果表明:用两种菌混合浸出的铜几乎等于嗜酸氧化亚铁硫杆菌单独浸出的铜;另外,亚铁的加入能提高铜的浸出.

Covellite oxidation was evaluated with two acidophilic thiobacilli that are important in bioleaching processes.The experiments were carried out in shake flasks in the absence and presence of 4 g/L Fe2+ (as ferrous sulphate) at pH 2.0, 150 rpm and 35 ℃. The tests showed that the copper extraction by the Acidithiobacillus ferrooxidans culture was nearly the same as that by the mixed culture of Acidithiobacillus ferrooxidans and Acidithiobacillus caldus. On the other hand, additional iron clearly improved Cu leaching.
