Our flotation cell, which has a volume of 600 cm 3, is built of borosilie glass, holds up to 90 g of sample, and achieves quartz and feldspar separation in ≤2 h for very feldsparrich samples. We trace the stepwise enrichment of quartz to 95 purity with our procedure by Xray diffraction analysis.

Flotation of quartz from quartzfeldspar mixtures by 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 ionic collector (amine) at pH 2–3 (O'Meara, 1939) (1979) reported that HF creates a large difference in ...

Starting from pegmatitic sand, the invention provides a method of purifying quartz sand, in which the amount of iron is reduced to less than ppm, the amount of zircon to less than 1 ppm, and the amount of phosphor to less than ppm. Gas nuclei are also removed. The method is carried out by washing with solution which contains at least 15% by weight of HF in water until at least 40% by ...

Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FTIR spectrum analysis, contact angle measurement and molecular dynamics (MD) simulation.
