摘　　要：某硫化-氧化混合钼矿生产钼尾矿Mo含量过高造成资源的极大浪费。试验研究在矿石性质研究的基础上,通过药剂制度和工艺流程的优化确定了尾矿再磨—预先脱泥—氧化钼浮选的工艺流程。针对氧化钼矿物难选的现象,研究开发了新型两性捕收剂α-氨基酸,实现了对钼酸钙矿物的有效回收。最终选矿指标:在Mo尾矿含Mo0.095%条件下,所得氧化钼精矿含Mo 8.120%,精矿中Mo总回收率达到了77.467%。Great waste of molybdenum resources was caused by high content of Mo in the molybdenum tailings which was produced from a sulfide-oxidized molybdenum ore. On the basis of the properties of the ore,the technological process including regrinding for tailings-preliminary desliming-floatation of molybdenum oxide was determined through optimization of process and reagents rules. The study developed a new-style amphoteric collector-α- amino acid to recycle the refractory calcium molybdate focused on the phenomenon of difficulty to recycling for molybdenum oxide. The final index is as following： while the run-of-time ores have 0. 34% of Mo,the molybdenum oxide concentrate contains 8. 120% Mo,the recovery rate of Mo is 77. 467%
