Mining and Processing. With the deposits generally occurring at the surface, as is the case with the Dingo Hole Silica, mining the material is more akin to a rock quarry and therefore relatively low cost. The more limited the processing requirements, the lower the total costs of production.
Raw Materials. Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. Silica is typically received in the form of metallurgical grade gravel. This gravel is 99.5% silica, and is 3 x 1 or 6 x 1 in (8 x 3 cm or 15 x 3 cm) in size.
Compounds of silicon have other important uses. They are used in the production of metal alloys. Silica is the principal ingredient in glass and ceramics. Silicon carbide is used as an industrial abrasive.
