Silicosis and Crystalline Silica Exposure and Mining: Information for Workers This fact sheet is also available in Portable Document Format (PDF). Silica is the common name for silicon dioxide, a white or colorless compound found naturally in sand, granite and many other types of rock.
In this section, data on exposures to crystalline silica (quartz) (see also the monograph on silica in this volume) as a component of the dust in coal mines are presented. For other exposure data, see Section Coal mine dust is a complex and heterogeneous mixture containing more than 50 different elements and their oxides.

and are a component of soil, sand, and rocks. Silica minerals are sometimes called "free silica," to distinguish them from other silicates, complex mineral structures containing bound silicon dioxide. Crystalline silica is a collective term that can refer to quartz, cristobalite, tridymite, and several other rare silica minerals.
