FLOTATION SEPARATION OF FELDSPAR -

It has been found that feldspars can be separated efficiently from feldspathic ores and minerals by means of froth flotation when a higher aliphatic amine salt and a higher aliphatic or aromatic sulfonate are used in conjunction as flotation reagents in a flotation medium made acidic with sulfuric acid, without the necessity for using hydrofluoric acid.

Flotation separation of Na-feldspar from K-feldspar by ...

2001-7-1  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.

2021-7-1  The primary gangue minerals in spodumene include feldspar and quartz (Rai et al., 2011, Tian et al., 2018, Xu et al., 2016) and flotation is the most commonly employed method for their separation, which is a significant process (Karrech et al., 2020, Tadesse et al., 2019). However, spodumene, feldspar, and quartz are silicate minerals, which exhibit similar surface properties.
