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.
