  • Flotation separation of Na-feldspar from K-feldspar by monovalent salts ...

    A major proportion of feldspar ores contain both Na-feldspar (Albite) and K-feldspar (microcline or orthoclase) in the same matrix, usually in quantities of about 3–5% Na 2 O and K 2 O. Despite their identical crystal structures and physicochemical properties, flotation appears to be the only plausible method of separating these minerals.
