In order to improve the utilization rate of a copper-tin mine, The fluorite resources in floating copper-sulfur-removal-magnet-tin tailings were reselected.Sodium carbonate was used as pH agent, water glass and acidic water glass as inhibitors, BK410A as collector.a roughing test, two scavenging, five cleaning of flotation test process. Finally, the fluorite concentrate was obtained and the CaF2 grade and recovery was 90.51% and 66.13%.
