Silica sand is found in the southeastern portion of the state. Five mines are currently known to extract silica sand for industrial applications. An unknown number of silica sand mines produce silica sand for construction and agricultural uses. Silica sand mines producing frac sand may or may not process the sand .
Geochemists also use the term "silica" to refer to the overall silicon and oxygen content of rocks. This is confusing, but stems from the fact that in rock analysis and sample is dissolved, the solution treated, and the amount of silicon present is determined by precipitating it as silica. So a geologist may say "This rock is 48% silica".
