Abstract: To achieve efficient utilization of fluorite resources in the tailings of an iron concentrator in Inner Mongolia, process mineralogy and flotation tests were carried out. The results showed that following iron removal by grinding and magnetic separation, flotation concentrate with CaF₂ grade of 97.12% and recovery of 85.73% was obtained by using sulfuric acid as pH regulator, sodium silicate as inhibitor, and L-1001 as collector through the closed circuit flotation comprising one roughing, nine cleaning, and two scavenging. Further, the fluorite concentrate with CaF₂ grade of 97.78% and full process recovery rate of 78.25% could be obtained through high intensity magnetic separation.
