| 摘 要： | 以活性炭、Ag+及Fe2+组合为催化剂，研究了催化条件下永平铜矿低品位原生硫化铜矿细菌槽浸的效果。研究结果表明，催化条件下低品位原生硫化铜矿细菌槽浸的效果良好，但充气量对浸出有较大的影响，其中25 mL/s的充气量最有利于铜的浸出，在浸出455 h后，铜的浸出率可达47.1%。酸化液可以代替9K＋S培养液作为溶浸剂，用酸化液作溶浸剂时，在浸出335 h后，铜的浸出率可达41.8%，比9K＋S培养液作溶浸剂高出1.7个百分点以上。

| Abstract: | Taking activated carbon,Ag+and Fe2+ as a combined catalyst,the vat bioleaching effect of low-grade primary copper sulfide ore from Yongping Copper Mine under catalysis conditions was investigated.The results showed that the vat bioleaching effect of low-grade primary copper sulfide ore was significant,but the aeration quantity had a great effect on the leaching.The aeration quantity of 25 mL/s was most beneficial to the leaching of copper,in this case,the leaching rate of copper reached 42.4% after 455 h le... |
