摘　　要：为了推动微细粒矿物的高效回收利用,从微细粒矿物的分选难题、基础研究和浮选药剂研究等方面进行了综合评述,深入剖析了微细粒矿物高效选择性回收的瓶颈问题。分析指出:微细粒矿物质量小、表面能大导致其较难分选;增大微细粒矿物的表观粒径,从而将微细粒难题转化为常规颗粒问题是微细粒回收的基本方向;组合捕收剂的开发与应用已经取得较为优异的成绩,也是未来微细粒分选药剂研究的热点方向。In order to promote the efficient recovery and utilization of micro-fine minerals,the separa⁃tion problems,basic research and flotation reagent research of micro-fine minerals were comprehensively re⁃viewed,and the bottleneck problem of efficient selective recovery of micro-fine minerals was deeply ana⁃lyzed.It is pointed out that the small mass and large surface energy of micro-fine minerals make it difficult to separate.Increasing the apparent particle size of micro-fine minerals and converting the micro-fine parti⁃cle problem into conventional particle problem are the basic direction of micro-fine particles recovery.The development and application of combined collectors have achieved excellent results,and it is also a hot re⁃search direction of micro-fine sorting reagents in the future.
