    Quartz-feldspar separation for the glass and ceramics

    May 01, 2007 Large reserves of feldspar ore exist in the Aegean region of Turkey. The main colored impurities in these ores are iron- and titanium-bearing minerals such as anatase, rutile, sphene and ilmenite. In this study, a potassium feldspar ore containing mainly quartz and coloring impurities was subjected to beneficiation tests involving magnetic-separation and

    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).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta

    Apr 01, 2016 The flotation separation of spodumene from other complex aluminosilicate minerals such as feldspar and mica, is problematic, due to their same active Al site for interaction with anionic collectors (Rai et al., 2011). In practice, the general method to accomplish effective spodumene flotation is to add amount of depressants associated with

    May 15, 2021 (3) For feldspar type aluminous ore, feldspar is a framework silicate mineral formed by the substitution of si4 + in quartz crystal by Al3+ and mixing with metal cations such as K+, Na+, etc., so the physical properties of feldspar and quartz are similar. Gravity separation and magnetic separation are difficult to separate feldspar and quartz
