| Abstract: |
| taking the sodium sulfide and Sodium hydroxide as leaching agent and using pressure-leaching to deal with complex antimony lead. Examining the factors to the influence of the leaching rate for antimony, such as,concentration of the sodium sulfide and sodium, leaching temperature, leaching time and the liquid-solid ratio. under the optimum conditions, antimony extraction rate can reach to 91.73%,leaching residue of antimony can reduce below 1%, effective separation in the crude ore antimony and lead. |
