It is extremely resistant to both mechanical and chemical attack, and thus the breakdown of igneous rocks containing it yields quartz grains which may accumulate and form the sedimentary rock sandstone. Also occurs in metamorphic rocks, as gneisses and schists, while it forms practically the only mineral of quartzites.
Hydrothermal quartz is an important substitute of crystal quartz that has been studied in detail because it is rich in SiO 2 [3,4].The hydrothermal quartz commonly contains a significant amount of associated minerals and fluid inclusions, which leads to difficulties in quartz processing [].Some primary and fine-grained mineral inclusions including mica, feldspar, and …
Quartz, some feldspars, and some nonsilicate minerals are relatively resistant to weathering because they contain more bonds, especially Si – O bonds, that do not break easily. It should not be surprising that minerals that characterize high-temperature igneous rocks, or those most often precipitated from water, are the first to decompose ...

Grinding, Sanding and Lapping The quartz crystal is then polished by grinding and sanding. The grinding wheel is dotted with very coarse bumps made out of an extremely hard material such as silicon carbide. It spins rapidly and is pushed against the quartz to slowly wear it away into a chosen shape.
In quartz process, the fine-grain grade with particle size below 0.1 mm is usually called slime.
