feldspar benifeciation without floatation process
Jun 25, 2019· Generally speaking, the feldspar concentrate rich in potassium and sodium is recovered by the combined mineral separation methods of gravity separation, electric separation, magnetic separation and flotation to remove associated minerals such as quartz and mica.
Feldspar Beneficiation & Flotation Process
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.
