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 ... -
Effects of bivalent salts on the flotation separation of Na-feldspar from K-feldspar
Demir, Cengiz; Bentli, İsmail; Gülgönül, İlhan; Çelik, Mehmet Sabri (Pergamon-Elsevier Science Ltd, 2003)Despite similarities in the physical and physico-chemical properties of Na- and K-feldspars, their flotation separation with monovalent ions exhibited a reasonable success. Further studies have been therefore initiated to ... -
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 ...
