Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. ...

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline (KAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8).
2. Ore washing and desliming The washing process is suitable for feldspar produced from weathered granite or feldspar placer, which mainly to remove impurities such as clay, fine mud and mica. On the one hand, it can reduce the content of Fe2O3 in feldspar ore, on the other hand, it can increase the content of potassium and sodium in feldspar ore.

Apr 07, 2013· 21 November 2015 Prof. Dr. H.Z. Harraz Presentation Feldspar Groups 48 Mineral processing • Feldspars are either selectively mined or processed by optical, flotation and/or electrostatic separation, in order to remove the accessory minerals (e.g. quartz, mica, rutile, etc.) present in the ore.
Feldspar is one of the most abundant minerals in the earth's crust. The feldspars include a range of compositions with the general chemical formula xAl(Al,Si) 3 O 8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K). The sodium and potassium-enriched compositions are known as alkali feldspars, which are primarily used in glass manufacture and ceramics.
The feldspars also crystallize as a vein mineral, are important constituents in many metamorphic rocks, and are found as grains in sedimentary rocks. Gem quality moonstone is found in cavities in gneiss and crystalline schists, less commonly in ore-mineral veins, and as pebbles in gravels.
