Selective flotation separation of feldspar in non fluoride medium

Oct 01, 2019 In this study, a selective flotation process for the separation of K-feldspar from Na-feldspar was developed for the beneficiation of a Norwegian microcline-quartz pegmatite sample. The K-feldspar flotation was performed in alkaline environment (pH 10.5–11.6) with only the addition of NaOH as a modifier and non-ionic Brij58 as a frother, on a

    Mar 01, 2015 This paper describes the application of non-hydrofluoric acid flotation methods used in feldspar-quartz separation and the comparison with conventional HF/amine method. In order to enhance the feldspar beneficiation, this study seeks to determine the mechanical and dielectric behaviour of ceramic based on floated feldspar. 2. Materials and methods

    Because the collectors used for non-sulphide flotation are generally non-specific, efficient separation requires knowledge of the response of feldspar to the different classes of collector. There have been many fundamental studies into the separation of feldspars from associated minerals using anionic and cationic collectors

    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

    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

    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 flotation, which were applied
