Research on the flotation separation of feldspar and quartz of a spodumene flotation tailings, explored the two flotation process of non-fluoride with acid and hydrofluoric acid. The hydrofluoric acid carried out the stirring time, hydrofluoric acid amount, dodecylamine amount and flotation time condition test, on the basis of condition test, the open-flow test and closed circuit test of feldspar flotation were determined. The results show that through the closed circuit test of"one roughing, two scavenging and one cleanings", the feldspar concentrate with the grade of 4.13%and recovery of 98.03%of K2O and the grade of 7.46%and recovery of 98.42%of Na2O was obtained. Production quality inspection show that the feldspar concentrate and quartz concentrate (feldspar flotation tailings) achieved industrial requirements, realised the purpose of comprehensive utilization of spodumene flotation tailings.
