Flotation methods were investigated for recovering fluorite and byproduct beryllium from the Fish Creek deposit of Nevada. The preferred method includes (1) fluorite rougher and cleaner flotation, (2) desliming at 20 um, (3) muscovite flotation, (4) silicate flotation, (5) hypochlorite wash of silicate concentrate, and (6) beryllium rougher and cleaner flotation from the silicate concentrate. Laboratory results showed that over 94% of the fluorite was recovered in a concentrate containing 96% caf2. Beryllium flotation produced concentrates containing in excess of 5% beo with recoveries over 70%. A 100-lb/h continuous flotation unit was constructed to demonstrate this procedure.
