摘要
原矿含有大量有机碳,金赋存状态复杂,属低品位原生金矿石。本选矿工艺采用优先浮碳,消除有害元素再选金,浮选尾矿氰化浸出的工艺流程,使难选金避免走原矿焙烧浸出的高投资、高成本运营的选矿工艺流程,综合回收率86.67%。
The ore contained large amounts of organic carbon, gold distribution state complex, is a native low-grade gold ore. The beneficiation process uses the priority floating-carbon, the elimination of harmful elements in reflotation of gold, flotation tailings leaching process, so that refractory gold ore roasting leaching to avoid taking a high investment, high-cost operation process, a comprehensive recoverv of 86.67%.
