Role of Mixed Collector Systems in Selective Separation of Albite from Greek Stefania Feldspar Ore [PDF]
, 2007 The adsorption behaviour of mixed cationic alkyl diamine and anionic sulfonate/oleate collectors and a combined cationic-anionic collector, N-tallow 1, 3-propane diamine dioleate (Duomeen TDO) at acidic pH values on albite and quartz minerals was ...

SYNTHESIS OF ALBITE AT 210–240 °C
, 1966 High temperature albite was synthesized at 210 and 240 °C from a mixture of kaolinite, NaCl, and Na2CO3, each run lasting about 63 days. Identification was made by X-ray diffraction, supplemented by electron microscopy.

Flotation and adsorption characteristics of albite and quartz with oleic acid-based collector
, 2023 The separation of feldspars from quartz is a challenging processing method as they have identical physical and physicochemical surface properties. To put forward the possible ways to separate them from each other is essential.

Initialer Magmatismus und seine Erzbildung in der Beleuchtung des Koli-Kaltimogebiets [PDF]
Bulletin of the Geological Society of Finland, 1969 In the Koli—Kaltimo area, North Karelia, Finland, the initial igneous activity of the Karelidic zone has produced diabase dikes and spilitic sills. Some of the sills have differentiated forming spilitic rock associations, which range from peridotite to ...
