摘　　要：江西铁路坎铜矿床是城门山铜矿床东延部分,是以铜硫为主,兼有金、银、铅、锌、钼、铁等多矿种的综合性矿床。铜硫矿体伴生金、银主要富集于1Cu矿体中。全区伴生金、银平均品位分别为0.17×10-6、12.93×10-6,金、银品位均随主元素铜品位增高而增高,矿区内金、银品位总体东南高,西北低。金主要以金的独立矿物和包裹金形式存在,属自然金范畴。银主要以银的硫化物和自然银形式存在。伴生金、银综合回收利用前景较好。Tielukan copper deposit is the east extension part of Chengmenshan copper mine,which is a comprehensive deposit mainly containing copper,sulfur and associated with gold,silver,lead,zinc,molybdenum,iron and so on.Associated gold and silver are mainly enriched in 1Cu(copper-sulfur ore)orebody,and average grades of Au,Ag are 0.17×10-6,12.93×10-6 respectively in the mining area.In addition,gold and silver grades both increase with the ascend of copper grade,and generally high in southeast and low in northwest.Furthermore,gold mainly exists in the form of independent minerals and related inclusions,all belong to the category of natural gold.And silver mainly exists in the form of sulfide and natural silver.Finally,the prospect of comprehensive recovery and utilization of associated gold and silver is fairly good.
