摘　　要：某难浸金矿石金品位3.18 g/t,采用常规氰化工艺金浸出率仅为65%左右,属于较难浸金矿石。试验研究查明了金浸出率不高的原因是矿石中存在斜方砷铁矿、毒砂所致,通过添加助浸剂对该矿石进行氰化浸出工艺的试验研究,结果表明添加助浸剂辅助氰化金浸出率提高25.47%。The gold content of a difficult leaching gold ore is 3.18 g/t, and the gold leaching rate of conventional cyanide leaching is about 65% ,which belongs to hard to leach gold ore. The experimental studly indicates that it is loellingite and arsenopyrite which affect the leading rate. By adding leaching agent, the results show that the gold leaching rate is increased 25.47%.
