| 摘 要： | 考察碱性硫化钠体系浸出某难处理含锑金精矿过程中金锑分离和综合回收,探讨浸出条件对金和锑浸出的影响,重点对该体系中金的浸出机理进行考察。结果表明,在硫化钠80g/L、氢氧化钠20g/L、常温条件下锑的浸出率达到95.3%,有10.3%的金伴随浸出,同时揭示了金浸出率随电位及温度变化的规律。

| 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. |
