Feldspar Beneficiation from Manisa Alaşehir PegmatitesGeneral Directorate of Mineral Research and Exploration (MTA), Turkey. ABSTRACT: Feldspar beneficiation on the samples from Manisa-Alaşehir pegmatites were investigated. Chemical analysis showed that the total alkali content of the samples was around 7-8% as the contents of. Fe: 0, and TiOi were 0.4 and 0.5%.beneficiation studies of the alkali feldspar granite,Alkali feldspar granite - WikipediaAlkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black.

Albite mineral is generally used in glass production, while microcline and orthoclase are used in . In previous studies, the removal of iron and titanium-bearing minerals (tourmaline, hornblende,.
work also indicated the potential to produce a significant amount of feldspar. The company, therefore, extended the feasibility study to research it more fully. .. products (Daniels, 2002b). Nepheline Syenite. In glass and ceramics, nepheline syenite, like feldspar, provides alkalis that act as a flux to lower the melting.
Feldspar plays an important role as fluxing agent in ceramics and glass application and also used as. functional fillers in the paint plastic, rubber and adhesive industries. It is found that the area of Aqaba city is the best for my study, because large amount of alkali feldspar granite. raw materials on the surface containing.

The area is accessible from the Red Sea through Wadi El-Dabbah desert track. The rock types exposed in the study area, starting from the oldest are metavolcanics, older granitoids, biotite granites and alkali feldspar granites. The metavolcanics (island arc volcanics) are the oldest rock units in the studied area (Fig. 1).
