Flotation of quartz from quartz-feldspar mixtures by the ...
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 cationic collector (amine) at pH 2–3 (O’Meara, 1939).

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.
Selective Flotation Separation of Feldspar in Non Fluoride ...
In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector. The bulk of amine collectors used in current feldspar operations are applied as the water-soluble acetates of the free-base amines.
Flotation separation of Na-feldspar from K-feldspar by ...
Feldspar has been traditionally separated from quartz using amine type cationic collectors and hydrofluoric acid as activator for feldspar (Shimoizaka et al.,1976; Malghan, 1981; Tang et al., 1993). El-Salmawy (1993) floated quartz from feldspar using an anionic surfactant in the presence of metal hydroxy complexes.

Complete flotation of quartz can be attained at 0.4 nonionic/anionic molar ratio Flotation separation of quartz from feldspar 1237 by using C12, C14, and C16 chain length sulfonates. Microcline is not floated in these systems and under the same conditions. 100 ~t o .0 4o .J u. 20 0 10 " mlerocllne.
Feldspar Beneficiation & Flotation Process
Feldspar Beneficiation & Flotation Process. 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. Dry recovery methods are economically limited to about 17% Al2O3.

Abstract. An improved process for separating feldspars from feldspathic ores by means of froth flotation wherein a combination of a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate is used as a flotation reagent, eliminating the necessity for activation with hydrofluoric acid.
How can I separate sand into its different components such ...
For separation of Quartz from Feldspar absolutely best way is application of selective flotation (depends on quantity of Quartz and Feldspar you can use Amine (cationic) collector using HF as surfactant (activator) of feldspar for separation of Quartz from Feldspar).

Quartz-feldspar flotation separation The trading flotation separation method of quartz-feldspar is the HF acid method. consider of the environment protection, most mineral workers prefer to …
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 stone activator (HF or NaF) in the flotation system, as ...
Review of flotation of feldspar: Mineral Processing and ...
Jul 18, 2013 · This stone reviews the application 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.
A New Flotation Technique for Feldspar-Quartz Separation ...
In this paper, the authors introduce a new flotation technique, a double collection flotation precess, which succeeds in separating feldspar from quartz effectively in weak acidic medium (pH = 5-6). In the presence of sodium hexametaphosphase(HMP), sodium oleate selectively improves the floatability of feldspar in the first collection step.
