  • Developing Effective Separation of Feldspar and Quartz Developing Effective Separation of Feldspar and Quartz

    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 system, as the

  • Separation of feldspar from quartz using EDTA as modifier Separation of feldspar from quartz using EDTA as modifier

    Nov 01, 1999 The following conclusions can be drawn from the data emerging from the studies on zeta potential and mineral fioatability under various conditions: 1--Quartz-feldspar separation is facilitated by the presence of EDTA at pH 2. 2--The best quartz-feldspar separation is obtained at concentrations of EDTA from 10-4M to 5x10-4M. 3~The use of a 3:1 cationic-anionic collector improves quartz

    in the purification methods as an effective way to separate quartz from feldspar. Nonetheless, it is not an standalone procedure to obtain pure quartz and must be combined with chemical methods when the sample is rich in feldspar minerals.

  • Separation of feldspar from quartz: Mechanism of mixed Separation of feldspar from quartz: Mechanism of mixed

    Aug 01, 2002 Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore. The single mineral flotation tests showed the feasibility of

    Keywords: Feldspar, Selective separation, Weathered granites, Flotation, Monovalent salts Granite and granodiorite deposits are widely scattered throughout in Eastern Black Sea region of Turkey. These granitic bodies also contain considerable amounts of quartz, Na-feldspar, K-feldspar, mica and other color-imparting ferruginous impurities

  • Re-examination of common extraction and purification Re-examination of common extraction and purification

    quartz samples contained small amounts of feldspars (3– 10%), indicating that neither density separation nor mag-netic separation can fully remove all feldspars, and that HF etching is essential. SEM/EDS mapping also showed that the alkali feldspar extracts contained some quartz grains (˘5%). Roughly15% Na-rich grains were observed within

  • Differential separation of albite from microcline by Differential separation of albite from microcline by

    Aug 01, 2003 Na-feldspar (albite) and K-feldspar (microcline or orthoclase) are major feldspar minerals with identical crystal structures and physico-chemical properties. Flotation appears to be a unique method of separating these minerals. Fundamental studies on an amine/feldspar system in the presence of monovalent salts have shown that separation of these feldspar minerals by flotation is
