Abstract：
In order to effectively improve the beneficiation indexes of a fluorite ore from Ejina Banner in Inner Mongolia,a large number of experimental studies had been carried out based on the study of the ore characteristics.The test determined that under the conditions of grinding fineness -0.074 mm 85%,water glass dosage of 1 000 g/t,oleic acid dosage of 120 g/t and pulp temperature of 35 ℃，fluorite concentrate with CaF2 grade of 98.22% and recovery rate of 88.33% was obtained via one roughing-four cleaning-one scavenging,middlings sequential returning flotation process flowsheet and ideal beneficiation indexes were achieved.
