| 摘 要： | 研究了氨性硫代硫酸盐体系中,碳质金矿中金的浸出行为,考察了硫代硫酸钠和氨水浓度,硫酸铜、硫酸铵用量对金浸出率的影响。结果证明:含碳质金矿中的金可被硫代硫酸盐溶液有效浸出。金的浸出率从氰化法的21. 22 %提高到90 %以上。实验证实活性炭不能有效吸附浸出液中的Au(S2O3)3-2络离子,这一独特性能可能使氨性硫代硫酸盐浸金体系成为碳质金矿中金的最有前途的回收方法。

| Abstract: | The behavior of gold dissolution on carbonaceous gold ores with ammoniac thiosulfate was studied in this paper. The influence upon leaching rare of gold about concentration of thiosulfate sodium, ammonia and using amount of CuSO4,(NH4)2SO4 was researched. It was affirmed that the gold leaching from include carbon gold ores is very effective with ammoniac thiosulfate solution and Leaching rate of gold rise from 21.22%(Cyanid leaching) to over 90%. It was discovered that Au(S2O3)3-2 was not adsorbed effectively by activated carbon with test. This characteristic will be make the system of ammoniac thiosulfates solution to a most promising reclaim method of leaching gold from carbonaceous gold ores in the future. |
