Minerals Free Full-Text Developing Effective Separation
Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al.  in an acidic environment (pH = 2.1).It was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz .However, there is a large amount of chemical activator (HF or NaF) in the flotation

Separation of Feldspar from Quartz: Mechanism of Mixed Cationic / Anionic Collector Adsorption on Minerals and Flotation Selectivity August 2002 Minerals and Metallurgical Processing 19(3):128-136
Electrostatic feldspar/quartz separation without
2000. 1. 1. Keywords: feldspar, quartz, electrostatic, polyelectrolytes, pollution, environment Introduction In the electrostatic feldspar-quartz separation an activation is done by heating and treatment with hydrofluoric acid. By that means a feldspar concentrate with >90% grade and a quartz with <5% feldspar is produced.
Quartz-feldspar separation for the glass and ceramics
2007. 5. 1. 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 flotation,
Separation of feldspar from quartz using EDTA as modifier
1999. 11. 1. Flotation responses of quartz and feldspar in presence of 10-4M EDTA and as a function of mixed ratios of anionic and cationic collectors at a constant total concentration of 20 mg/1, pH 2.1. 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.
Rock magnetism of quartz and feldspars chemically
2018. 9. 26. The quartz and feldspars account for 2.3–22.7 wt% of the samples. X-ray diffraction analyses detect both plagioclase feldspar and potassium feldspar. Plagioclase is albite-rich and abundant in the top ~ 7.4 m of the core. Potassium feldspar mainly occurs below ~ 10.4 m.
