摘　　要：针对安徽某大型钼矿尾矿开展了尾矿资源综合利用试验研究。研究在尾矿性质的基础上确定了脱泥—强磁除铁—钾长石浮选的工艺流程。针对传统的长石-石英分离采用的氢氟酸工艺易引起剧毒和强腐蚀性的缺陷,研究开发出新型阴阳离子捕收剂在合适的配比条件下实现了长石与石英的有效分离。最终选矿指标:在钼尾矿含K_2O 4.89%的条件下,最终钾长石精矿含K_2O 10.24%,精矿中K_2O回收率为51.79%。The comprehensive utilization experiment from tailings resource on a large molybdenum ore was conducted. On the basis of properties of the tailings,the technological process including desliming-impurity eliminating by strong magnetic separation-potassium feldspar flotation was determined. Focusing on the major defect that traditional hydrofluoric acid feldspar-quartz separation technology could cause danger of highly toxic and strong corrosive,new anion-cation collectors were developped to achieve the highly effective separation between feldspar and quartz under under suitable conditions. The final beneficiation index is: while the run-of-time ores have 4. 89% of K_2O,the potassium feldspar concentrate contains 10. 24% K_2O,the recovery rate of K_2O is 51. 79%
