云南播卡金矿的矿石颗粒微小、含炭质高。在该金矿石工艺矿物学研究的基础上,对比分析了原设计单位推荐的矿石处理方案,指出对氧化矿拟用全泥氰化炭浸、原生矿拟用浮选加重选的工艺流程,减少了因矿样含炭质高而降低金的回收率的影响,同时使得各项生产指标十分理想,金回收率高达90%左右。 Yunnan sow card gold ore particles are small, with carbonaceous high. Based on the study of process mineralogy of the gold ore, the ore treatment scheme recommended by the original design unit is comparatively analyzed. The process flow of flotation re-election for the planned flotation of natural ore is proposed for the reduction of Due to the high carbon content of ore samples, the gold recovery rate was reduced, and the production indicators were very satisfactory. The gold recovery rate was as high as 90%.
