摘　　要：为了回收河北某矿石中的元素金,对该矿矿石进行了氰化浸金及混汞试验研究。在原矿金品位23.6 g/t,磨矿细度-200目含量为91.2%,NaCN用量为2.5 kg/t,浸出时间24h条件下,获得了浸渣金品位0.403 g/t,金浸出率为98.29%的氰化浸出指标。混汞金回收率为48.86%。The experimental study of cyanide and mix-mercury was done to recovering gold from an ore in Hebei province.The index of gold grade of leaching residue 0.403 g/t,gold leachng rate by cyanide being 98.29% wase got on the condition of crude grade of gold was 23.4 g/t,gringing size being-0.074 mm 91.2%,the dosage of NaCH 2.5 kg/t,leaching time being 24 h.mix-mercury recovery of gold is 48.86%.
