Abstract

Although feldspar ore from the industrial mineral class, which has abundant reserves in the earth's crust, has many areas of use, especially in the ceramic and glass industry, it has an important share in Turkey's export items. To be employed in industry, feldspar ore, which typically contains impurities like rutile, iron, and titanium, must have a high impurity level. The flotation process is frequently used to enrich the feldspar ore, which is enhanced using a variety of techniques depending on the reserve content.

In this study, feldspar concentrate with low iron concentration was obtained using the flotation process to be employed in a variety of industries. The study's findings lead to a reduction in iron content in feldspar concentrate to 0.2% Fe2O3 with 11.61% K2O content, whereas separate concentrations of oxide concentrate with 6,53% Fe2O3 content, mica concentrate with 64,80% SiO2 content, and quartz concentrate with 84,95% SiO2 content were also obtained.
