| Abstract: |
| The separation and comprehensive recovery of gold and antimony from Sb-bearing gold concentrate with in alkaline and sodium sulfide system were investigated. The effects of leaching conditions on leaching of gold and antimony were discussed. The gold leaching mechanism in this system was explored. The results show that the leaching rate of antimony at room temperature is 95.3% above accompanied with 10.3% leaching rate of gold under the conditions including sodium sulphide of 80 g/L and sodium hydroxide of 20 g/L. The relationship between gold leaching rate of potential and temperature is revealed. |
