摘　　要：某钼矿老尾矿钼品位为0.0063%,矿物成分考查表明,该尾矿中钼主要以辉钼矿形式存在,采用一次粗选,一次扫选,以煤油为捕收剂的浮选流程,得到产率为66.49%,品位为0.73%,回收率为77.04%的粗钼精矿。粗钼精矿通过再磨再选,可得到钼精矿产率为2.31%,品位为24.87%,作业回收率为79.68%的技术指标。The grade of molybdenum in tailings from a molybdenum mine is 0.006 3% and the molybdenum elements mainly exist in the form of molybdenites. Using the flowsheet with one roughing and one scavenging, adding coal oil as collector, the rough concentrates are obtained, of which the yield is 66.49%, the grade is 0.73% and the recovery is 77.04%. The rough molybdenum concentrates are milled and flotated again. The yield of final flotation concentrates are 2.31% ,with the grade of 24.87% and the recovery of 79.68%.
