【摘要】 对大宝山野生细菌进行了调查 ,并对废矿堆铜矿石进行了多元素及化学物相分析 ,应用驯化的菌株对矿样进行浸出铜的试验研究 ,研究表明 ,在不加催化剂的情况下 ,A矿样浸出 2 5d,铜浸出率达 2 5% ,B矿样浸出 1 0 d,铜浸出率达 79%。对浸出过程的机理研究证实了细菌对铜矿物的氧化分解作用。更多还原

【Abstract】 The wild bacteria resources are investigated.The elementary and phase analysis of Dabaoshan’s discarded copper ores are performed.The experiments of extracting copper from Dabaoshan’s discarded copper ores and are proceeded with trained strains.The results show that the copper leaching rate of B mine sample is up to 79% after 10 days and the leaching rate of A mine sample is 25% after 25 days,The study on the mechanism of leaching process has verified the oxidation and decomposition effect of bacteria on the copper minerals.更多还原
