摘　　要：东乡铜矿是一个以铜为主,共(伴)生有铁、钨、金、银、硫的多金属矿床。矿石中伴生的金、银多呈独立矿物存在,主要嵌布在斑铜矿和石英的晶界上或充填在裂隙中。对伴生金、银的空间分布和富集规律进行了分析,做到合理配矿,提高了矿山的经济效益。The Dongxiang copper deposit,with copper as the major ore mineral,associates with Fe,W,Au,Ag,and S,is of polymetallicore type.Gold and silver associated with the ores occur as independent minerals and distribute on the crystal interface of borniteand quartz or fill into the fissures.After an understanding of the spacial distribution feature and richment regularitv of the gold andsilver associated with the ores,making up a favourable burden with rich and poor ores in a reasonable ratio will bring about moreeconomic benefit for the mine.
