Study on the Separation of Feldspar from Quarty by

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 ...

2002-8-1  Using pure albite and quartz minerals, the separation of albite from quartz using mixed cationic/anionic reagent schemes is assessed through Hallimond flotation, zeta potential and diffuse reflectance FTIR studies. The reagent schemes are tested in bench-scale flotation for the separation of albite from Greek Stefania feldspar ore. The single mineral flotation tests showed the feasibility of ...

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

Feldspar is separated from quartz by a method using HF as an activator and a method using diamine and petroleum sulfonate. This study discussed the effects of particle size on these two methods. A flotation using HF is capable of separating feldspar from quartz when the particle size is {minus}210+10{mu}m.

GChron - Isolation of quartz for cosmogenic in situ

In the course of extracting carbon from quartz we have, on multiple occasions, observed concentrations of in situ 14 C that were anomalously high and in excess of geologically plausible maximum concentrations. We hypothesise that the elevated in situ 14 C concentrations are sourced from part of the widely used mineral separation procedure known as froth flotation, a process that relies on ...
