Silicon ore body refers to the mineral substance of silicon that can be mined, not to the ubiquitous nature of silicon compounds. The content of elemental silicon in the earth's crust accounts for 25.7% of the total weight of the earth's crust, and it is the most abundant element after oxygen.
Silicon and oxygen have a strong affinity, so there is no free-flowing silicon in nature. Mainly in the form of its oxides and silicates. Silicon oxides are mainly sand, quartz, crystal, purple quartz, agate, flint and opal. Silicate mainly consists of granite, amphibole, asbestos, feldspar, clay and mica.
Silicon and its derivatives are very useful material, silica glass production is the main raw material, sand and clay are building industrial raw materials, silicate is the main raw material, manufacturing porcelain enamel and pottery silicon is an important additive in steel and aluminum alloy, organic silicon and monocrystalline silicon is the backbone of high-tech product material, so the natural silicon ore mining and processing is one of the important industrial area.
