Removal of mica from feldspar ore by spiral concentrator

gated. Mica is the primary source of iron in these kinds of ores. The objective behind this practise is to remove the mica from the ore and to obtain low concentration with small amount of iron. For this purpose, a sodium feldspar ore was used and the effects of process variables on the separation of mica by using spiral were investigated. Ac-

Lecture 9: Silicates: Mica and Feldspar

Lecture 9: Silicates: Mica and Feldspar Phyllosilicates Joining two chains of SiO4+ tetrahedra leads to the double chains in amphibole. Adding more chains indefinitely leads to sheets of SiO4+ tetrahedra that are the building blocks of phyllosilicates. The other building blocks are octahedral sheets.

Beneficiation of albite is mainly performed by separation methods including gravity, magnetic, and flotation. Although the concentration scheme is usually dependent upon the quality of the end product, flotation is the most widely used beneficiation method. Floatability of albite using cationic reagents is maximum in the pH range of 8 to 9. Feldspar-quartz separation is achieved only at low pH

Removal of titanium impurities from feldspar ores by new

Dec 01, 1998 The principal impurities in some feldspar ores are titanium and iron, which impart color and in turn degrade the quality of the ore. Mineralogical investigations on the majority of Turkish feldspar ores indicate that rutile and, scarcely, sphene are the major titanium minerals and iron mainly originates from mica minerals.
