Feldspar is highly valued commercially , because of its numerous uses.
Feldspar is regarded as the most abundant group of minerals which can be found on the earth's crust. It is a tectosilicate mineral and tectosilicate minerals constitute about 72-75% of the earth crust and are one out of many silicate minerals which are rock-forming minerals which also constitute about 85-90% of the earth crust.
It has a colourless or pale-coloured crystals appearance and contains alumina silicates of potassium, sodium, and calcium.
Feldspars are formed from magma as a crystallize veins in igneous and metamorphic rock, most feldspars are deposited as sodium feldspar, potassium feldspar and mixed feldspars.
Feldspar is found in different colors such as white, pink, brown, or gray. This mineral belongs to the tectosilicate group. In case of a pure mineral, each of the crystal has an uneven pattern, and are found grouped together. They are opaque and have a glassy luster.
Is used for their alkali content and alumina in industries. Used in production of floor tiles, shower basins and tableware.
Is used for ceramics and glassmaking such as glass for drinking, protection glass and fiberglass for insulation. It is sometimes used as a filler and extender in paint, plastics, and rubber.
