Na-feldspar (albite) and K-feldspar (microcline or orthoclase) are major feldspar minerals with identical crystal structures and physico-chemical properties. Flotation appears to be a unique method of separating these minerals. Fundamental studies on an amine/feldspar system in the presence of monovalent salts have shown that separation of these feldspar minerals by flotation is …
[Introduction]: According to different feldspar mineral types and ore properties, Xinhai customizes a series of feldspar processing technology, including magnetic separation, flotation, gravity separation and combined technology.So as to achieve the removal of mica mineral impurities, etc., to obtain potassium and sodium feldspar concentrate, aiming to obtain high-grade feldspar concentrate.
During the course of measuring the zeta potential of feldspar, it was noticed that the time required for the mineral suspension to reach equilibrium (prior to any reagent addition) was significantly longer than that for the other two minerals (16 h compared with 1–2 h for mica and quartz).
Electrostatic shape separation was considered to be an adequate technique for processing a particulate mixture of flake mica and isometric granules of feldspar and quartz. The authors carried out ...
Quartz is a basic material in industrial production. The simplest use is as a filter and absorbent, foundry sand, filler or abrasive, etc. In some high-tech industries, the application of quartz is also very extensive and important, such as the production and manufacture of ultra-pure quartz, high value-added quartz, especially optical fibers, monocrystalline silicon, etc., which can be used ...

SELECTIVE SEPARATION OF Na- AND K-FELDSPAR FROM . multivalent salts, a required selectivity in flotation is achieved. Sodium ions depress Na-feldspar during the flotation of alkali feldspar at natural pH and in HF medium in the presence of an amine type collector, Genamin-TAP [4,5].
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 ...
The best results were achieved with a combination of high-intensity wet magnetic separation and flotation. A feldspar concentrate containing 16.28% Al2O3, 10.75% K2O,2.84% Na2O,69.97% SiO2 and 0 ...
Jul 27, 2020· 01 1. The separation with iron minerals in quartz extraction technology. Iron is the common impurities in quartz sand. The existing form are as follows: (1) existing in clay or kaolinized feldspar; (2) attached on the surface of quartz particles as iron hydroxide film; (3) existing in ilmenite and other heavy minerals; (5) existing in mica, hornblende and other mineral particles.

The purpose of quartz flotation process is to remove the non-magnetic associated impurities, such as feldspar, mica. These impurities are similar to quartz in element composition and structure, which is difficult to separate from the quartz. The quartz flotation process can be divided into fluorine flotation process and fluorine-free flotation ...
In all three experiments on sample "Bujanovac" (class −0.6 to +0.063 mm), in the first phase mica was floated, feldspar in the second. Quartz sand stayed in the underflow ().From Table 2 it can be seen that the chemical composition of the mica concentrate obtained in all three tests was almost the same (SiO 2 =51.00%, 50.83%, and 50.79%, respectively; I.L.=4.23%, 4.72% and 4.53% ...
