1999-11-01  Separation of feldspar from quartz using EDTA as modifier 1397 In fact, when PDP:PS ratios in favour of the anionic PS are adopted, separation does not occur. However, it does become possible on passing to ratios in favour of the cationic PDP, the maximum being at a 3:1 ratio. CONCLUSIONS A study has been made of the influence exerted by EDTA in quartz-feldspar separation

An alternative process which exhibited effective separation of quartz and feldspar while recycling the tailwater from the flotation was proposed. The effect of hydrofluoric acid (HF) pretreatment on flotation of feldspar and quartz using dodecylamine (DDA) as collector was investigated by micro-flotation, zeta potential, pyrene fluorescence spectroscopy, attenuated total reflection flourier ...

Feldspar flotation as a quartz-purification method in ...

The presence of feldspar in sediment samples poses a challenge to the separation of quartz and affects the chemical procedures for extracting the radioactive CNs 10 Be and 26 Al. Additionally, feldspar contamination reduces the 26 Al/ 27 Al ratio, thus hinders the accurate determination of 26 Al by accelerator mass spectrometry (AMS).
