| 摘 要： | 钻井沟金矿主要的矿石类型为含金多金属硫化物石英脉和含金白云母石英岩,矿石结构以粒状晶结构、碎裂结构和包含结构为主;构造主要为块状构造和浸染状构造。金矿物为自然金,以裂隙金为主,少量包裹金,金矿物以中粗粒金为主,载金矿物为黄铁矿、黄铜矿和石英。矿石中金的品位高,赋存状态简单,有害元素砷、锑、硫、碳等的含量低,属易浸型矿石。采用浮选—氰化联合工艺流程,金的综合回收率可以到达99.24%。

| Abstract: | The ore of Zaunjinggou gold deposit mainly consists of gold-bearing quartz vein rock with multimetal sulfide and gold-bearing muscovite quartzite, which are characterized by granular crystal, cataclastic and poikilitic texture, while massive and disseminated structure. The gold mineral are native gold, most of which exist in the fissure, and some of them are gold inclusion, gold bearing mineral are pyrite, chalcopyrite and quartz. |
