Research on Separating Low-Grade K-Feldspar from Quartz without Hydrofluoric Acid

Abstract:

Flotation technology without fluorite was studied to separate low-grade K-feldspar with quartz. It is shown in the results that qualified K-feldspar concentrate can be gained by grinding, desliming, flotation and high intensity Magnetic Separation process. Feldspar concentrate obtained in closed-circuit had a content of K₂O and Na₂O 12.12%, quartz concentrate with a yield of 19.94% containing 97.12% SiO₂was obtained in the same time.
