| 摘 要： | 本文依据早子沟金矿矿区勘查及选矿工艺矿物学研究资料,从金矿石的结构构造、矿石类型、矿物成分、金的赋存状态及其主要载体矿物的嵌布特征、共伴生组分等方面综述了矿石质量特征,重点分析了以上矿石质量特征要素对选矿的影响;简述了选矿试验研究的成果及选别效果。矿区矿石工艺类型属少硫化物微细粒浸染型含金矿石,金的赋存状态复杂,利用重选—浮选中矿再磨的重浮联合流程可获得较理想的选冶回收指标。

| Abstract: | In the light of research resuks of exploration and process mineralogy for Zaozigou gold mine, the paper described the quality of ore from such aspects as texture and structure of ore, ore type, mineral composition, gold occurrence and main gold-bearing minerals; it is focused on the characteristic factors which would affect the result of ore dressing. From the process technology, the ore is micro-fine granular disseminated gold ore with a little of sulfide, the method combined gravity separation, flotation and re-grinding middle products will get the expected recovery results for beneficiation and metallurgy. |
