研究可见光和银离子(Ag^(+))对嗜酸氧化亚铁硫杆菌浸出p型和n型黄铜矿(黄铜矿A和黄铜矿B)的不同影响及机理。通过霍尔效应试验、生物浸出试验、X射线衍射、扫描电子显微镜和X射线光电子能谱对黄铜矿的半导体性质、生物浸出行为、表面形貌、主要物相和表面物种进行分析。实验结果表明,黄铜矿A比黄铜矿B具有更高的载流子浓度和更大的载流子迁移率,因此其溶出速率更快。生物浸出24 d后,当光照和Ag^(+)同时存在时,黄铜矿A的铜浸出率为91.05%,比黄铜矿B的铜浸出率(73.19%)高17.86%。显然,可见光和Ag^(+)对黄铜矿A生物溶解过程的促进作用强于黄铜矿B,这主要归因于黄铜矿A具有更高的载流子迁移率。此外,在光照影响下,黄铜矿表面电荷转移加快,导致Ag2S积累增多(特别是黄铜矿A),从而导致钝化层致密结构被破坏,钝化效果降低,黄铜矿溶解加速。

使用生物淋洗处理黄铁矿废石,从源头上缓解其产生酸性矿山废水(AMD)的风险。生物淋洗结果显示,在嗜酸氧化亚铁硫杆菌(***)的作用下,40天内可以从黄铁矿废石中去除近82%的铁和硫。动力学研究结果表明,废石中黄铁矿的去除主要受化学反应和内扩散控制。X射线衍射(XRD)和X射线光电子能谱(XPS)的结果表明,在***细菌介导下,生物源黄钾铁矾能够钝化废石中残余的黄铁矿。对渣样进行二次生物浸出,试验发现溶液pH没有明显下降,且仅有8 mg/L和160mg/L的铁从两个黄铁矿废石渣样中溶出,表明渣样的酸和铁释放能力得到削弱。
