Abstract: There is 18.58% CaF₂ in a lead-zinc mined tailings from Hunan，the main impurity composition is SiO₂ and CaCO₃.In order to provide the basis of the fluorite recovery and utilization of tailings，beneficiation experiment was conducted on the ore.The results indicated that,CDG100 mm×100 mm cycle pulsating high intensity magnetic separator was used to remove iron，non magnetic products with Na₂CO₃ as regulator，Na₂S and sodium silicate as inhibitor，acidification sodium silicate (ratio of sulphunic acid to sodium silicate is 2∶1) as depressor for cleaning,Z-202 as collector，by one roughing，seven cleaning，one scavenging closed circuit flotation test process，fluorite concentrate with CaF₂ grade of 94.76%，recovery rate is 53.83% was obtained.Test results can provide technical guidance for comprehensive utilization of lead-zinc mined tailings containing fluorite.

Key words: Tailings containing fluorite, Iron removal by magnetic separation, Flotation
