 — Their results are provided in Fig. 13. The recovery of K-feldspar increases from 86.73% to 92.21% as the Ba2+ concentration is increased to 1.1×10âˆ'2 mol/L. After that, the recovery of K-feldspar decreases. The optimum Ba2+ concentration to enhance the flotation of K-feldspar is 1.1×10âˆ'2 mol/L.

 — The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na2SiF6; SF) as a selective depressant was investigated. Moreover, the influence mechanism of SF on the selective flotation …

 — The principal mineral components of the sized fractions were feldspar, quartz, pyrite, calcite, and biotite. There were lesser amounts of titanium-bearing minerals—mainly rutile, some muscovite, and chlorite, plus minor amounts of zircon, chalcopyrite, and molybdenite. ... Rutile flotation without grinding the plus 200-mesh material is ...

There are numerous physical and chemical separation methods for reducing iron content in feldspar ores. Generally, while-500+75 µm sized feldspar ores beneficiate by physical and physicochemical separation …

Large reserves of feldspar ores exist in the Aegean region of Turkey. Unlike conventional ores, the main impurity in some of these deposits is titanium. In this study, the results of testwork carried out to determine flotation conditions for efficient separation of titatium bearing minerals from two different feldspar ores from the area are presented. The study …

 — The principal impurities in some feldspar ores are titanium and iron, which impart color and degrade the quality of the ore. Mineralogical investigations indicate that, while titanium originates mainly from rutile with small amounts of sphene, iron originates mainly from mica minerals. Fatty acids, particularly oleic acid, are extensively used, with …
