近年来,我国在安徽、江西、湖南、云南、贵州、广西、广东等省区发现了大量含砷金矿床。据报导,这类金矿石汉湖南就有储量×××吨以上,占该省金总储量的55%左右。这类金矿石普遍被认为是难处理的矿石。目前国内对这类矿石的开发利用进展较迟缓,这与我国四化建设迫切需要黄金的形势很不相称。我们认为,这类矿石开发利用进展迟缓的原因之 In recent years, a large number of arsenic-bearing gold deposits have been discovered in Anhui, Jiangxi, Hunan, Yunnan, Guizhou, Guangxi and Guangdong provinces.
