【摘要】 氧化亚铁硫杆菌是一个具有很强生物浸矿能力的细菌,本文对3株分离得到的氧化亚铁硫杆菌及一株来自菌种中心(Acidithiobacillus ferrooxidans A．f)的铁氧化活性及其这些菌株对低品位黄铜矿浸出速率进行了研究。结果显示,在所有的4株A．f菌中,菌株CMS—F1和F10—ATCCC23270的铁氧化活性较高,其对黄铜矿生物浸出速率也高。进一步分析亚铁氧化活性对生物浸矿效率的影响时发现,在A．f菌中,氧化活性高的菌株,其对低品位黄铜矿的生物浸出效果也高。更多还原

【Abstract】 Acidithiobacillus ferrooxidans is a kind of bacteria being famous for its capability of bioleaching.In this study,the ferrous iron-oxidazing capability and efficiency of low grade chalcopyrite bioleaching from four Acidithiobacillus ferrooxidans were measured.The results showed that the ferrous iron-oxidazing capability and efficiency of chalcopyrite bioleaching from CMS- Fland F10-ATCCC23270 strain were higher.The analysis of the influence of ferrous iron-oxidazing capability on efficiency of chalcopyrite bioleaching revealed that the strain with the higher ferrous iron-oxidazing capability had higher efficiency of low grade chalcopyrite bioleaching.更多还原
