01/11/2016  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).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta ...

Differential Flotation of Some Egyptian Feldspars for ...

It is now possible to free feldspar from all kinds of gangue minerals, e.g. mica, quartz and heavy minerals in addition to separation of both K and Na feldspars from each other [2]-[4]. Cationic flotation of feldspar (amine + HF) in presence of NaCl was conducted by CengizDemir of Turkey in 2010 to separate both Na- and K-feldspar [3]. NaCl addition controls amine adsorption on sodium feldspar ...

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.
