难选金矿石,又称为难处理金矿石,通常为高砷高碳型和微细粒浸染型金矿石。这类金矿石往往经细磨后仍有相当一部分金不能用常规的氰化方法有效地浸出。我国这类资源丰富,分布较广。从1978年在贵州省册亨县发现国内第一个高砷高碳微细粒浸染型难选金矿至今,通过10几年的地质勘探工作,相继在全国16个省(区)发现了这类难处理金矿,远景储量非常可观,将成为我国“八五”

Refractory gold ore, also known as difficult to deal with gold ore, usually high-arsenic high-carbon type and micro-disseminated gold ore. These gold ores are often still finely milled after a considerable portion of gold can not be effectively leached by conventional cyanidation methods. Our country is rich in such resources and has a wide distribution. Since 1978, the first high-arsenic, high-carbon, fine-grained, refractory gold mine in China was discovered in Chhengchuan County, Guizhou Province. So far, geological exploration work has been carried out for 10 years and one after another in 16 provinces (districts) across the country Difficult to deal with gold, long-term reserves is very impressive, will be China’s “Eighth Five”
