Abundant reserves of Nafeldspar (albite) and Kfeldspar (orthoclase or microcline) are found in granites, syenite, tracite and pegmatites. As both feldspar minerals have similar chemical structure and physicochemical properties, their separation is challenging. Flotation is known to be the only technique to enable their separation.

A major proportion of feldspar ores contain both Nafeldspar (Albite) and Kfeldspar (microcline or orthoclase) in the same matrix, usually in quantities of about 3F% NazO and KsO. Despite their identical crystal structures and physicochemical properties, flotation appears to be the only plausible method of separating these minerals. In this study, amine f7otation together with zeta

The difference in surface charge between the minerals at pH 2 was found to be the basis for preferential feldspar flotation from quartz in mixed diamine/sulfonate collectors. The infrared spectra revealed no adsorption of sulfonate collector when used alone but displayed its coadsorption as diaminesulfonate complex when used with diamine.
