摘　　要：重选一直是黑钨矿选别的主要方法,但其对微细粒矿物分选的效果却较差,浮选法才是解决细粒级矿物分选的较好途径.近年来,我国微细粒黑钨矿浮选研究取得了一定进展,但生产实践方面仍存在不足之处.从微细粒黑钨矿的特点出发,简单介绍了微细粒黑钨矿的浮选新工艺、浮选药剂等,并讨论了它们各自的特点和适用性.并对近几年来微细粒黑钨矿相关浮选理论研究及矿物应用实例进行了综述,对钨矿山相关生产有一定的参考作用.Gravity separation is an important method to wolframite separation, but its effect on the microgran-ular mineral separation is poor. Flotation is the best way to ultrafine mineral separation. In recent years, the research of ultrafine wolframite in China has achieved certain progress, but there are many problems in respect of actual production yet. Based on the characteristics of the ultrafine wolframite, this paper introduces the new technology in the flotation of ultrafine wolframite, flotation reagents, etc., by discussing their characteristics and applicability. The theoretical researches and application cases of ultrafine wolframite are reviewed and can be used for reference in the rrelavent manufacturing process of the tungsten mines.
