Oct 29, 1974· 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.
This paper 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.
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 .

This paper 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 ...
Potassium feldspar and quartz are all silicate 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 cation mixed collector was studied in the paper.
Jun 25, 2019· Flotation separation of potash feldspar and albite The separation of potash feldspar (orthoclase and microcline) and albite is a challenging issue because they are mostly mixed in feldspar deposits and these minerals have similar chemical structures and similar physical chemistry properties.
HF pretreatment resulted in leaching of SiO2 and enrichment of Na, K and Al on the feldspar surface. Consequently, the negative surface charge of feldspar increased at pH 2, which allowed for the flotation separation of the feasible minerals.
Flotation Separation Of Feldspar - Flotation process for separating silica from feldspar to form . A separation process is provided for treating a feed material comprising silica, feldspar, and metal . Learn More . Differential Flotation of Some Egyptian Feldspars
Apr 01, 2016· Read "Selective flotation separation of spodumene from feldspar using new mixed anionic/cationic collectors, Minerals Engineering" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.
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.
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 application Serial Number 117,470.
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.
In the present study, from experimental results, a new concept of possibility of flotation separation of quartz from feldspar is presented. The effect of the nonionic surfactant Brij 58 on the flotation behaviour of quartz and feldspar has been investigated. The effect of the surfactant adsorption at the solid-liquid interface was also studied.
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.

L&M Heavy Industry is committed to provide the global customers with the first-class products and superior service, striving to maximize and optimize the interests and values of the customers, and build bright future with high quality. ...
Jul 18, 2013· This paper 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.
If the content of mica and iron is low, it will enter the flotation separation of quartz and feldspar directly after graded desilting. If the content of impurities such as mica and iron is high, it is necessary to remove the impurities such as iron and mica by flotation first, and then carry out the separation and flotation of feldspar and quartz.
US6098810A Flotation process for separating silica from. A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass.
Selective Flotation of Quartz and Feldspar Using Non-Ionic Surfactant T Wakamatsu1 and M S El Salmawy2 ABSTRACT EXPERIMENTAL In order to develop the HF-free flotation reagent system, the main objective of this investigation was to study the possibility of separation of Materials quartz from feldspar using non-ionic surfactants as the collector.
