| Abstract: |
| Based on the redox potential difference of the different metal sulphides, in view of the refractory pro perty of the complex metal sulphide ores containing Cu, Pb, Zn and Ag The experiment adopts the method of controlling redox potential in the leaching process of the bulk concentrate containing the complex metal sulphides of Cu?Pb?Zn and Ag, and selectively leach each valuable element in different stages On the other hand, by adding selective precipitation?replacement?extraction technology and so on, the experimental technique effectively separated and extracted the valuable elements under the condition of high recovery from the bulk concentrate On the best process condition, the leaching rates of Cu, Pb, Zn and Ag are all more than 99 0%, the recovery of element sulphur is more than 76% |
