    Conventional Feldspar Flotation Using HF Since the inception of the feldspar flotation process using hydrofluoric acid by O’Meara the process has achieved a great commercial success. In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector.
