Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity silicon

Silicon (Si) is a light chemical element that combines with oxygen and other elements to form silicates. Silicon in the form of silicates constitutes more than 25% of the Earth's crust. Silica (SiO₂) as quartz or quartzite is used to produce silicon ferroalloys and silicon metal. Demand for silicon ferroalloys is driven principally by the production of cast iron and steel. Silicon metal, which generally is produced like ferrosilicon in submerged-arc electric furnaces, is used not as a ferroalloy, but rather for alloying with aluminum and for production of chemicals, especially silicones. Small quantities of silicon are processed into high-purity silicon for use in the semiconductor industry.

We are in the process of transitioning our datasets to the USGS ScienceBase platform to enhance long‑term accessibility, documentation, and version control. In addition to the established format published on this page, Mineral Industry Surveys beginning with the 2026 editions are now available in a ScienceBase data release, to which data from subsequent reporting periods will be appended.
