Silica Minerals represent the group of minerals being composed of silicon and oxygen forming the chemical formula SiO 2. Silica can occur in macrocrystalline, crytocrystaline and amorphous form. Industry predominantly uses the crystalline form of silica, i.e. quartz. Silica is used as granular products containing the particle size range >63 µm.
Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
