| 摘 要： | 研究低品位原生硫化铜矿嗜热嗜酸菌强化浸出过程。结果表明,嗜热嗜酸菌对低品位原生硫化铜矿的较强适应性 需经较长时间的连续驯化才能获得。浓酸熬化、添加Ag 均能强化低品位原生硫化铜矿嗜热嗜酸菌的浸出效果,而添加黄铁矿精 矿会降低其氧化浸出作用。

| Abstract: | The intensified leaching processes of the primary ore of copper sulfide with thermoacidophile, KY-2 strain, are investigated. The results show that the adaptability of thermoacidophile to the primary ore of copper sulfide can be achieved by culture continuously in long term. The leaching process is intensified by the sulfuric acid curing and addition of Ag , but addition of pyrite concentrate is harmful to leaching process with thermoacidophile. |

| Keywords: | metallurgical technology primary copper ore bio-leaching thermoacidophile intensified leaching |
