  • Selective flotation of K-feldspar from Na-feldspar in

    The K-feldspar flotation resulted in a K-feldspar concentrate of 14.3 K 2 O at 77 K-feldspar recovery and K 2 O/Na 2 O ratio of 10.4. The NaOH conditioning of the fluorine-amine activated feldspars resulted in rapid desorption of fluorine and the selectivity of the process was assumed to result from the more rapid desorption of fluorine
