The Feldspar mineral is mined from large granite bodies from pegmatites (formed when the last fluid stages of a crystallizing granite becomes concentrated in small liquid and vapor-rich pockets that allow the growth of extremely large crystals), and from sands composed mostly of feldspar.
is the name given to a group of minerals distinguished by the presence of
alumina and silica (SiO2) in their chemistry. This group
includes aluminum silicates of soda, potassium, or lime. It is the single most
abundant mineral group on Earth. They account for an estimated 60% of
exposed rocks, as well as soils, clays, and other unconsolidated sediments, and
are principal components in rock classification schemes. The other minerals included
in this group are the orthoclase, microcline and plagioclase feldspars.
The Quartz is a chemical compound consisting of one part silicon and two parts oxygen (SiO2). It has a hardness of seven on the mohs scale which makes it very durable. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. Quartz sand is used in the glass industry , electronic industry and in petrochemical industries.
