摘　　要：针对贵州丹寨难处理金矿,提出了焙烧预处理—密闭氰化浸出—活性炭吸附提金新工艺,进行了处理量为10 t的半工业化试验研究。结果表明:Au浸出率87.74%,Au解析率98%,Au总实收率72.38%。The half industry extraction process for refractory concentrates gold in Danzhai Guizhou province was introduced. The effects of roasting pretreatment, hermetic cyanide leaching, leaching and adsorption of activated carbon were investigated. The results show that the leaching rate of Au can reach 87.74%, the desorption rate of Au reaches 98% and the total of recycling rate reaches 72.38%.
