Location of industrial sand extraction site

Industrial sand refers to sand with a high percentage of quartz, thus having a fairly pure SiO2 content.  Many industrial uses for sand require that it be pure, inert, and resistant to high temperatures.  High purity industrial sand is used in glass making, ceramics, filtration, hydraulic fracturing, and in chemicals.

Industrial (silica) sand is presently mined at a single location in Virginia. COVIA conducts surface mining and mineral processing at facilities located near Gore in Frederick County.  The material is mined from the Devonian-age Ridgeley Sandstone. In 2019, the company reported total production of about 556 thousand short tons, down about 4 percent from the tonnage reported in 2017.

Annual production and estimated value1


1 Estimates of annual mineral value are calculated using tonnages reported to DMME and commodity sales prices reported in numerous published and unpublished sources. The prices may include national or global industry averages. The calculated annual values do not necessarily reflect the actual sales prices received by mine operators in Virginia.
