    Froth flotation is a commonly used procedure for separating feldspars and micas from quartz for the preparation of quartz mineral separates to carry out cosmogenic nuclide analysis. Whilst extracting carbon from quartz we observed in situ carbon14 ( 14 C ) concentrations which were anomalously high and in excess of theoretical geological maximum concentrations.

    Abstract Experimental studies of flotation of quartz particles, under various conditions and cells (setups), are presented. Pure and wellcharacterized quartz samples were treated with a commercial alkyl ether monoamine as flotation collector with bubbles in various sizes: coarse bubbles (400–800 μm); nanobubbles (200–720 nm); and their mixtures.

    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 ionic 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 ...
