Understanding the flotation separation of Na and K ...

Dec 01, 2018  Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were investigated in the presence of K + ion as counter ion. In order to identify the role of K + ions on the selective separation of feldspar minerals, solubility, adsorption ...
