2016-11-1  1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta ...

Flotation of quartz from quartz-feldspar mixtures by

Abstract Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was produced.
