Feldspar Beneficiation & Flotation Process. Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery methods are economically limited to about 17% Al2O3.

Feldspar typically contains a range of impurities, including iron oxides, mica and silica. These impurities can reduce the quality and value of feldspar and make it less suitable for specific applications. Usually, flotation and magnetic separation methods are used to solve this feldspar mineral processing problem.

2. Flotation process. The flotation process can effectively remove iron from clay and fine-grained iron-containing minerals, but the effect is not good for hard ores. For severely weathered ores, secondary sludge may be produced during the crushing and grinding stage, which may easily cause the flotation to be highly viscous, resulting …
