| 英文摘要 | Heap bioleaching-solvent extraction-electrowinning is applied in Monywa copper mine to produce A grade cathode copper in Myanmar. Chalcocite is the main copper mineral and quite high amount of pyrite is also included in the ore. During the process of extracting valuable copper from heap bioleaching, a part of pyrite was also oxidized and dissolved into the ferric sulfate and sulfuric acid, which has the adverse effect on the industrial production system. The main traits of Monywa Kyisintaung heap bioleaching practice were introduced. The pyrite content of Kyisintaung ore is about 12.98%. The acid balance during heap bioleaching is reached basically when the oxidation of pyrite reaches 3.31%. Combined with the historical industrial data, the critical factors related to pyrite oxidation were analyzed and the acid balance situation in the future was evaluated. It is suggested that the industrial heap bioleaching of Kyisintaung ore will probably be acid excessive. Some possible solutions are proposed to solve this challenge. 漏 2022, China Science Publishing & Media Ltd. All right reserved. |
