Flotation of quartz from quartz-feldspar mixtures by the

Nov 01, 2016 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).TON (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta
