Item type:Article, Access status: Open Access , Investigation on possibility of opaque minerals removal from foid bearing rock(Wydawnictwa AGH, 2009) Özün, Savas; Atalay, Ümit; Kadioğlu, Yusuf KaganFoid bearing rocks are one of the most major felsic intrusive rocks of Central Anatolian Crystalline complex (CACC) which are observed at the inner part of central Anatolia, Kirsehir, Turkey. Foid bearing rocks are mainly constituted from three different subunits: nepheline syenite, nepheline diorite and nepheline gabro. Nepheline syenite is represented the abundant lithological composition of alkaline magmatic rocks in the region. In this study the removal of mica, (ilmenite) iron-titanium oxide and magnetite minerals in Nepheline Syenite rocks from Central Anatolian Crystalline Complex, Turkey is investigated by flotation at alkali condition following to this high intensity wet magnetic seperation (HIWMS) was applied. The best results were obtained from - 106 + 38 microns particle sizes nepheline syenite feed. A concentrate with 7.84% $K_{2}O$, 11.22% $Na_{2}O$, 0.22% $Fe_{2}O_{3}$ and 0.01% $TiO_{2}$ content was produced with of 62.5% recovery by weight.
