Concentration of K-feldspar from a pegmatitic feldspar ore by flotation
Karagüzel, Cengiz; Gülgönül, İlhan; Demir, Cengiz; Çınar, Mehmet Ulaş; Çelik, Mehmet S. (Elsevier Science Bv, 2006)Abundant reserves of Na-feldspar (albite) and K-feldspar (orthoclase or microcline) are found in granites, syenite, tracite and pegmatites. As both feldspar minerals have similar chemical structure and physicochemical ... -
Differential separation of albite from microcline by monovalent salts in HF medium
Demir, Cengiz; Gülgönül, İlhan; Bentli, İsmail; Çelik, Mehmet S. (Soc Mining Metallurgy Exploration Inc, 2003)Na-feldspar (albite) and K-feldspar (microcline or orthoclase) are major feldspar minerals with identical crystal structures and physico-chemical properties. Flotation appears to be a unique method of separating these ... -
Interaction of sodium ions with feldspar surfaces and its effect on the selective separation of na- and k-feldspars
Gülgönül, İlhan; Karagüzel, Cengiz; Çınar, Mehmet Ulaş; Çelik, Mehmet S. (Taylor & Francis Inc, 2012)K-feldspar and Na-feldspar exhibit similar mineralogical, chemical and surface properties. Froth flotation is known to be the only technique to enable their separation. Our earlier studies revealed a good selectivity in ... -
Selective separation of sodium and potassium feldspar minerals from orebodies
Demir, Cengiz; Karagüzel, Cengiz; Gülgönül, İlhan; Çelik, Mehmet S. (Trans Tech Publications Ltd, 2004)Feldspar minerals are major commodities used in the production of glass and ceramics. A major proportion of feldspar rocks such as granites, pegmatites and nepheline syenites embody both Na-feldspar (Albite) and K-feldspar ... -
Surface vs. bulk analyses of various feldspars and their significance to flotation
Gülgönül, İlhan; Karagüzel, Cengiz; Çelik, Mehmet S. (Elsevier Science Bv, 2008)Cationic separation of Na-feldspar (albite) and K-feldspar (microcline) was earlier reported to be possible in the presence of monovalent salts. However, contrary to this result, the floatability of a series of K-feldspar ... -
Understanding the flotation separation of Na and K feldspars in the presence of KCl through ion exchange and ion adsorption
Gülgönül, İlhan; Çelik, Mehmet S. (Pergamon-Elsevier Science Ltd., 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 ...
