production of silicon from quartzites
r BOX I44
Silica occurs primarily as quartzite, vein and pegmatite deposits. Quartzite deposits have the best potential for eco nomic development. British Columbia has two major quartzite units, the Mount Wilson and Nonda formations, suit able for use in the manufacture of silicon, ferro silicon and silicon carbide.

Minerals | Silica
Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone. As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.
