摘要
本文采用一种新型捕收剂XL-2实现了在低温条件下的萤石浮选。XL-2具有良好的萤石选别效果和较强的抗低温性能,采用两段磨矿,一次粗选,一次扫选,七次精选,中矿1返回扫选,其余中矿顺序返回的闭路流程,获得了CaF2品位97.82%、回收率87.26%的精矿产品。
In this paper, fluorite flotation at low temperature has come true by using a new collector （XL-2）. The new collector was possessed of favorable flotation effect and higher resistance to low temperature. Adopting the closed circuit which includes two-stage grinding, one roughing, one scavenging and seven concentrates, middling 1 returns to scavenging and others return orderly, a fluorite concentrate with the grade of 97.82% and recovery of 87.26% was obtained.
