| 摘 要： | 采用浸矿菌浸出高砷铜精矿中的铜, 研究了浸出作用机理。通过比较浸出前后高砷铜精矿表面的变化和浸矿菌的吸附情况, 并结合浸出过程铁离子的变化对铜的浸出率的影响, 发现高砷铜精矿生物浸出的主要作用机理是间接作用机理。

| Abstract: | Leaching bacteria was used to leach copper in high arsenic-bearing copper concentrate.The leaching mechanism was studied.Based on the observation of the change of the surface of high arsenic-bearing copper concentrate before and after the leaching and the impact of iron ion concentration on the copper extraction in the leaching process,it is found that an indirect mechanism predominates in the bioleaching of high arsenic-bearing copper concentrate. |

| Keywords: | bioleaching high arsenic-bearing copper concentrate leaching mechanism leaching rate leaching bacteria |
