摘　　要：针对陕西某钼选厂精选尾矿中难选微细粒辉钼矿不能充分回收和利用的问题,通过采用铜钼混浮-铜钼分离原则流程,利用旋流-静态微泡浮选柱对其进行了再选回收试验研究。工业生产实践表明:采用旋流-静态微泡浮选柱能够获得钼品位31.096%,回收率62.71%的钼精矿产品,年创造利润2 078.22万元,提高了矿产资源的综合利用率。According to the inadequat recovery and utilization of micro-fine molybdenite in molybdenum cleaner tailings in a molybdenum plant in Shaanxi, a cyclonic-static micro bubble flotation column was performed for the re-covery of micro-fine molybdenite by the flotation process of copper-molybdenum bulk flotation and separation. The results show that the grade of molybdenum concentrates was 31 . 096%, the recovery rate was 62 . 71%, the annual profit was 20 millions 782. 2 thousands yuan, which improved the comprehensive utilization of mineral resources.
