摘　　要：为综合回收某白钨矿加温浮选尾矿中的萤石资源,采用“磨矿-水置换浓缩-萤石浮选”工艺,在给矿CaF_(2)品位25.47%条件下,获得了CaF_(2)品位92.35%、回收率60.59%的萤石精矿。In order to comprehensively recover fluorite resources from the tailings left after hot flotation of scheelite, a beneficiation process consisting of regrinding, water displacement and concentration, and fluorite flotation was proposed. It is shown that with the feed ore with CaF_(2)grade of 25.47%, a fluorite concentrate can be obtained with CaF_(2)grade and recovery at 92.35% and 60.59% respectively.
