Quartz is a chemical compound consisting of one-part silicon and two parts oxygen. It is the most abundant mineral found at Earth’s surface and its unique properties make it one of the most useful natural substances. Quartz is the second most common mineral in the Earth’s continental crust. It is made up of a lattice of silica (SiO2) tetrahedral.

It goes by an array of different names. The most important distinction between types of quartz is that of macro crystalline (individual crystals visible to the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals visible only under high magnification).

Quartz is also known as a ubiquitous mineral with an enormous number of uses.Quartz Processing (Silicon dioxide, SiO2) At a share of approx. 12 %, quartz ranks second behind feldspar as the most common mineral of the lithosphere, either in the form of solid rock or eroded sand.

After being processed to quartz sand < 600 ?m, the quartz is used in the manufacture of glass; for special paints (road building); in foundries as molding sand; in adhesives for the ceramics industry; in sand blasting equipment; for sanding sports stadiums; etc.

Even finer in the < 80 ?m range with a steep particle size distribution is found in ceramic base compounds, and at a fineness of < 20 ?m in glazes.It has a hardness of 7 on the Mohs’ Scale which makes it very durable.Quartz is silicon dioxide [chemical formula is (SiO2)].
