| 摘 要： | 研究了脆硫锑铅矿、铁闪锌矿、磁黄铁矿的细菌摇瓶浸出, 结果发现, 脆硫锑铅矿不能被细菌浸出;磁黄铁矿细菌浸出23 d, 铁的浸出率为99%;铁闪锌矿细菌浸出29 d, 锌的浸出率为91%, 铁的浸出率为15%。矿浆浓度对磁黄铁矿和铁闪锌矿的细菌浸出有影响。利用X 射线分析了3种矿物的细菌浸出机理。 |
| 关 键 词： | 脆硫锑铅矿 铁闪锌矿 磁黄铁矿 细菌浸出 X射线衍 射 |

| Abstract: | Three sulfide minerals, jamcsonite, pyrrhotite and marmatite, were leached in shaken flasks. The results show that jamcsonite is not leachable, after leaching for 23 days the leaching rate of iron in pyrrhotite is 99%, and after leaching for 29 days the leaching rate of zinc in marmatite is 91% and the leaching rate of its iron is 15%. The pulp concentration has effect on the leaching rate of pyrrhotite and marmatite. By analyzing of the leaching residue with EDXA, their leaching mechanism was discussed. |
| Keywords: | jamcsonite marmatite pyrrhotite bioleaching EDXA |
