One synchronized tailings in Yunnan contains fluorite 7.92％,silicon dioxide 32.16％,and calcium carbonate 12.35％,it belongs to quartz-type high-silica fluorite ore.The detailed mineral processing experimental study was developed based on process mineralogy analysis,and according to synchronized tailings fluorite features.Adoption of YSB-1 as the collecting agent,water glass and YSY-1 as the mixed inhibitor depressor,using of mine concentration returns flow of fluorite cleaning concentration operation,it obtained the fluorite concentration that the grade is 90.05％,the recovery rate is 62.05％,it realized the recycling utilization of synchronize tailings low grade fluorite.
