1974-10-29 · If the amount of the flotation reagent is increased, the resulting feldspar has a reduced content of Al 2 O 3 and Fe 2 O 3, although the yield of feldspar itself is increased. Therefore, the amount of the flotation reagent should be selected depending upon desired quality of the recovered feldspar and the separation efficiency.
2012-2-14 · AbstractThis paper reviews the appliion of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the published information on feldspar flotation relates to fundamental studies seeking to
2015-11-9 · An anionic-ionic flotation of two Egyptian feldspar samples, representing Road Ashaab locality of the Eastern Desert of Egypt, was investigated on both laboratory and pilot plant scales. The pegmatites belong to the alkali feldspar granite type, mostly microcline and orthoclase, KAL Si3O8 coarse grained rocks. Quartz, as the main gangue mineral, occurs in two forms as either free grains or
2018-4-5 · 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
2018-6-8 · AbstractThis paper reviews the appliion of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves.

2019-4-26 · Metallurgical ContentThe Feldspar Beneficiation & Flotation Process FlowsheetFeldspar Ore CrushingFeldspar Ore GrindingFiltering and Drying of Feldspar ConcentrateDes and Conditioning Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores.
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 transformed infrared spectroscopy (ATR-FTIR), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and bench scale flotation.
The invention is especially applicable to the froth flotation and/or table concentration of feldspar from quartz and the separation of feldspar from other associated minerals. It is a continuation in part of appliion Serial Nuer 117,470.
flotation separation of feldspar from quartz. Flotation of quartz from quartz-feldspar mixtures by 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
2010-5-2 · Selective separation of Na- and K-feldspar from weathered granites by flotation in HF medium Ceramics – Silikáty 54 (1) 60-64 (2010) 63 concentration to determine the effect of amine on the selective separation of albite from orthoclase, seen in the Figure 5, the most efficient separation with high K2O
The selectivity in flotation separation of spodumene from other pegmatic aluminosilies such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult.

2019-4-26 · Table of ContentsConventional Feldspar Flotation Using HFThe Non-Hf Feldspar Flotation MethodProcess DescriptionExperimental Results Feldspathic deposits occur widely throughout the United States, but North Carolina, California, Connecticut and South Carolina accounted for over 80% of the total domestic feldspar output for the year 1973.
2015-11-5 · However, a HF-free flotation process using a mixture of the ionic and anionic collectors for the separation of feldspar from sand was described by Katayanagi  and the process was reported to be applied in industrial practice  . In an aqueous medium the feldspar surface shows, after a short time, changes which have a neg-

Potassium feldspar and quartz are all silie minerals with frame structure,and have the similar crystal structure and physicochemical properties. Therefore, flotation has become the main method to separate potassium feldspar from quartz. The separation of potassium feldspar from quartz with anion and ion mixed collector was studied in the paper.
2018-6-8 · more than one feldspar mineral, and flotation conditions for the separation of individual feldspar minerals have been developed to produce individual feldspar minerals for specific appliions. Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine collector at neutral or acidic pH values.
