Abstract: 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 1returns to scavenging and others return orderly,a fluorite concentrate with the grade of 97.82%and recovery of 87.26% was obtained.
