Flotation Experimental Study of Associated Fluorite in a Tungsten Polymetallic Ore
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.
