摘要:
青海某含砷含碳微细浸染型金矿石氧化率达40 %，易泥化绢云母相对含量达26 %。针对该矿石性质，进行了选矿工艺研究。结果表明：采用原矿全泥氰化、重选、浮选等单一流程，金回收指标均不理想；采用精扫选、中矿分流浮选—尾矿再磨、环保浸金剂浸出联合工艺，在正交试验获得的最佳条件下，可获得金精矿金品位31.95 g/t，金总回收率88.05 %的较好指标，实现了金的高效回收。

Abstract:
The oxidation rate of a microfine disseminated arsenic and carbonaceous gold ore from Qinghai is 40 %,and the relative content of sericite prone to argillization is 26 %.According to the ore properties,the mineral processing technology was studied.The results show that the gold recovery index is not ideal by using single processes such as run-of-mill ore all-sliming cyanidation,gravity separation and flotation;under the optimal conditions obtained by orthogonal tests,the joint process combining cleaning and scavenging,middlings persion flotation-tailings regrinding,and environment-friendly reagent leaching can obtain the gold concentrate with gold grade 31.95 g/t and the total recovery rate of gold is 88.05 %,which is good,realizing the efficient recovery of gold.
