Froth Floatation
After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes …
Review of flotation of feldspar
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.
Froth flotation of feldspar
Froth flotation of feldspar is one of the most important methods to obtain high recovery of feldspar in the ceramic and glass industries. Very good separations of feldspar from the other gangue minerals such as quartz, iron, silica, and tourmaline need to be done.
Froth Floatation
After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic.
THE INTERACTION OF FELDSPAR, MICA AND QUARTZ …
Series of experimental work for direct feldspar flotation on non-magnetic fraction at different dosage. Contact angle values of feldspar and quartz in diamine concentrations at pH 6 and pH …
Feldspar flotation as a quartz-purification method in …
We present a new froth flotation mineral-separation device and procedure that allows for very effective quartz enrichment before CN chemistry. Our flotation cell, which has a …

Froth flotation of mixed feldspar
In order to upgrade mixed feldspars, froth flotation (Rau, 1985) could be applied to separate feldspar from those micas and iron-bearing minerals, and quartz respectively. The purpose of this research was to study about the processing of mixed feldspar including characterization, flotation and evaluation respectively. 2. Methods.
Flotation of quartz from quartz-feldspar mixtures by the …
This study demonstrates a high flotation separation selectivity between quartz and different types of feldspar, and that quartz can be readily floated from feldspar in diluted solutions of hydrofluoric acid (HF) by the aid of a frother.
Feldspar flotation as a quartz-purification method in …
We present a new froth flotation mineral-separation device and procedure that allows for very effective quartz enrichment before CN chemistry. Our flotation cell, which has a volume of 600 cm 3, is built of borosilicate glass, holds up to 90 g of sample, and achieves quartz and feldspar separation in ≤2 h for very feldspar-rich samples. We ...

A Comparative Study of Quartz and Potassium Feldspar …
An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation …
THE INTERACTION OF FELDSPAR, MICA AND QUARTZ …
Series of experimental work for direct feldspar flotation on non-magnetic fraction at different dosage. Contact angle values of feldspar and quartz in diamine concentrations at pH 6 and pH 2 using HF acid as pH controller.
A Comparative Study of Quartz and Potassium Feldspar …
Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be selectively floated from quartz. Recovery rates depended on reagent choice, pH levels, HF modifier dosage, and HF conditioning time.

Review of flotation of feldspar
Potassium feldspar can be floated from sodium feldspar in a sodium chloride solution with an amine collector at neutral or acidic pH values.
