| 摘 要： | 应用驯化的氧化亚铁硫杆菌对大宝山废铜矿石进行了浸出铜的试验研究。结果表明, 次生硫化矿(辉铜矿)浸出10 d, 铜浸出率可达79%;对原生硫化矿(黄铜矿)浸出25 d, 铜浸出率达25 %。氧化亚铁硫杆菌浸出铜的机理在于其氧化分解了矿石中的黄铁矿、黄铜矿、辉铜矿及其它硫的化合物。

| Abstract: | A study was made of extracting copper from Pabaoshan′s discarded copper minerals using acclimatized T. Ferrooxidants. The results showed that secondary sulfide ore was leached for 10 days, obtaining a leaching rate of 29% Cu and primary sulfide ore for 25 days, obtaining a leaching rate of 25% Cu. The mechanism of leaching copper using T. ferrooxidants lies in its ability to oxygenate and decompose pyrite, chalcopyrite, chalcocite and other sulfides of copper. |
