Study on the Separation of Feldspar from Quarty by Flotation

Mechanisms of the separation of feldspar from quartz by flotation, using cationic collectors (long chain amine) in acid circuit with hydrofluoric acid have been discussed. In the acid solution, the adsorption amount of dodecyl ammonium acetate (DAA) on feldspar which had previously been treated with hydrofluoric acid was larger than that on the

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 chemical activator (HF or NaF) in the flotation system, as

Jul 18, 2013· Abstract. 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.

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.
