Silica is a "building block" material that forms rocks, soil, sand, and other parts of the earth. A large amount of the earth is made up of silica. Silica occurs in either a crystalline or an amorphous structure. Over many years, silica in the soil can form into crystalline silica due to natural heat and pressure.
Quartz deposits are widely dispersed in nature, but the presence of ore bodies capable of yielding high-purity quartz is exceedingly rare. As a result, the effective purification and processing of high-purity quartz from natural siliceous materials has emerged as a prominent area of research within the non-metallic mineral processing …

Quartz is one of the most common minerals in the Earth's crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering.
