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. The problem in feldspar flotation is to recover slime free …
