| 摘 要： | 本文比较了不同预处理条件下砷金矿中金的浸出行为，探讨了高砷金矿中砷的脱除效果和影响金的浸出率的原因。研究证实，氨性硫代硫酸钠溶液对高砷金矿中的金具有优异的浸出性能，该方法省去了各种复杂的预处理过程，金的浸出率从常规氰化法的15％提高到约90%。

| Abstract: | Leaching behavior of gold arsenic gold ore was compared by different methods of preliminary treatment in this paper,arsenical removal effictiveness from high arsenic gold ores and cause affecting leaching rate of gold was researched.It was approved that the ammoniac thiosulfates sodium solution is very excellent reagents for leaching gold from height arsenic gold ore,this method can omit the complicated processes of variety preliminary treatment,and leaching rate of gold can be raised from routine method of cyanid leaching 15% to approximate 90%. |
