A tungsten polymetallic mine was associated with fluorite resources,and its tungsten flotation tailings contain 19.66％ CaF2,45.01％ SiO2 and 2.99％ CaCO3,which has comprehensive recovery and utilization value.For the associated fluorite ore,the process mineralogy studies and flotation test research were conducted,using AP for fluorite flotation collector,GA for cleaning depressor,after closed-circuit flotation test of one roughing,seven cleanings,the fluorite concentrate with CaF2 grade of 95.60％ and CaF2 recovery of 67.74％ was obtained.It has realized the compre-hensive recovery of the associated fluorite resources.
