Silica Dust Control In-Depth
Common Sources of Silica
Silicon dioxide is formed into a crystalline structure over millions of years. Thirty percent of all minerals are silicates (minerals containing silica), and geologists estimate that they could comprise up to 90 percent of the earth’s crust. The amount of RCS in any specific dust emission is based upon the silica concentration in the material and the application.
