Abstract: CaF2 grade of the fluorite associated with a tungsten polymetallic ore tailings is 25.07%,in order to effectively recover the fluorite resource and realize the comprehensive utilization of the resource,beneficiation test was conducted.The results showed that using sodium oleate as collector,acidified sodium silicate and sodium hexametaphosphate as inhibitor,fluorite concentrate with CaF₂ grade of 94.89%,SiO₂ grade of 1.55%,CaCO₃ grade of 0.34%,CaF₂ recovery rate of 68.12% was obtained via the closed process of one roughing-one scavenging-rough concentrate regrinding-seven cleaning,middling 1and midding 2 returning to scavenging,other midding sequence return to scavenging.The purpose of comprehensive recovery of fluorite resources was achieved,economic benefits was remarkable.
