摘　　要：新疆某地的蚀变凝灰岩型金矿石中主要载金矿物是臭葱石、黄铁矿和毒砂,金呈微细粒包裹于其中,同时矿石"泥化"严重并含少量有机碳,常规氰化金的浸出率在40.95%,属于难浸矿石。为了提高金的浸出率,采用预处理后氰化获得了93.89%的浸出率,同时探讨了采用石硫合剂浸出该矿石,并获得了93.51%的浸出率指标。The main gold-bearing minerals in altered tuff-type gold ore in Xinjiang were allium,pyrite and arsenopyrite,in which gold was wrapped as fine grains,while the ore was"muddy"and contains a small amount of organic carbon.The leaching rate of conventional cyanide gold was 40.95%,which belonged to refractory ore.The leaching rate of 93.89% was obtained by cyanidation after pretreatment.At the same time,the leaching rate of the ore by lime sulphur was studied experimentally,and the leaching rate index of 93.51% was obtained.
