After being puriifed by the process of selective crushing - classiifcation -wind separation, a muscovite mica tailing from Sichuan province was as taken the research object. A principle process of flotation with mixed anionic/cationic collectors in alkaline condition was used. The flotation conditions are as follows: the grinding ifneness is -0.074 mm covering 49.78%, the overall dosage of mixed collector (mass ratio of sodium oleate and dodecylamine being 3∶1) is 240 g/t, and the dosage of pH adjusting agent Na2CO3 is 1000 g/t (pH = 9.0), the dosage of inhibitor sodium silicate is 300 g/t. Under the above optimal conditions, the closed circuit lfotation lfowsheet with one-stage roughing, two-stage concentrating, one-stage scavenging and returning of middling in turn were used,the muscovite micaconcentrate with muscovite mica grade of 98.71% and a 84.40% muscovite mica recovery can be obtained.
