摘　　要：内蒙古某钼铋多金属硫化矿,含钼0.65%,含铋1.12%,钼铋品位较高,有较大的工业回收价值.采用"混合浮选—钼铋分离"的选矿工艺回收该矿石中的有用矿物,以乙硫氮和煤油作为捕收剂进行混合浮选,以硫化钠和亚硫酸钠作为组合抑制剂,煤油为捕收剂进行钼铋分离,最终实验室小型闭路试验可以获得含钼47.31%,钼回收率89.52%的钼精矿以及含铋42.64%,铋回收率86.04%的铋精矿,较好地实现了钼铋分离.A molybdenum-bismuth polymetallic sulfide ore in Inner Mongolia contains high grade of molybde- num （0.65 %） and bismuth（1.12%） which has a high industrial recovery value. The process of ＂mixed flotation- separation of molybdenum-bismuth＂ was carried out to recover the useful minerals. The diethyldithiocarbamate and kerosene were used as collector in mixed flotation. The sodium sulfide and sodium sulfite were used as composite depressant and kerosene as collector for molybdenum-bismuth separation. The small closed-circuit test eventually obtains a molybdenum concentrate with 47.31% of molybdenum and 89.52 % of molybdenum recovery and a bismuth concentrate with 42.64 % of bismuth and 86.04 % of bismuth recovery. The separation of molybdenum-bismuth is realized.
