用硫代硫酸钠从某卡林型金矿石中浸出金试验研究
|
摘要
研究了用硫代硫酸钠从贵州某卡林型金矿石中浸出金,考察了不同因素对金浸出率的影响。结果表明:在Cu~(2+)浓度为0.01mol/L、Na_2S_2O_3浓度为0.3mol/L、乙二胺浓度为0.06mol/L、液固体积质量比5∶1条件下常温浸出4h,金浸出率达72.87%,浸出效果较好。
Leaching of gold from a carlin-type gold ore from Guizhou province using thiosulfate was researched.The effecs of single factors on leaching rate of gold were examined.The results show that under the conditions of Cu~(2+) concentration of 0.01 mol/L,Na_2S_2O_3 concentration of 0.3 mol/L,ethylenediamine concentration of 0.06 mol/L,and the liquid-to-solid ratio of 5∶1,the normal temperature,the gold leaching rate is 72.87%.The leaching effect is better.
