摘　　要：滇西某选钨尾矿主要有价矿物为绿柱石,另外还伴生有萤石等可回收的矿物,针对滇西某选钨尾矿的矿石性质特点,研究采用浮选回收萤石—反浮选回收绿柱石的工艺流程,确定了萤石浮选和反浮选工艺条件。闭路试验从BeO品位为0.85%的尾矿中得到了BeO品位为7.5%,回收率为60.65%的绿柱石精矿,取得了良好的技术指标,实现了对含铍矿物资源的综合回收,达到综合回收的目的,具有一定的参考价值。The main valuable mineral of a wolfram tailing in western Yunnan is beryl and such recoverable minerals as fluorite were also associated. According to the properties of wolfram railings in western Yunnan, study on the process of fluorite flotation and reverse flotation of recovering beryl was carried on and the process conditions was determined. Through the closed-circuit test, the grade of BeO was improved from 0.85 % to7.5% and the beryl concentrate with the beryl recovery of 60.65% was obtained.The good technical indexes were obtained, the comprehen-sive recovery of beryllium minerals resources was realized. Of course, this technology has some reference value.
