Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.

5263 Edmund Highway West U.S. Silica's Columbia plant is located in the "Sandhills" of the Carolinas. These "Sandhills" consist of high-grade silica that is perfect for filtration, frac and geothermal grout. 2496 Hancock Road Mining the Oriskany deposit along the Warm Springs Ridge for over 100 years.
Our silica sand is as high as 99.65% quartz. It is hard, chemically inert, and has a high melting point of 3,115° F (1,713° C), making it ideal for various applications. We mine and process our silica sand as both whole and ground silica, and we offer our silica sand products in various ways: Dry or damp. Coated. Ultra fine to coarse.
As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2 ), having a specific crystalline form (hexagonal). It is found is all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering. When quartz-bearing rocks become weathered and eroded, the ...
December 12, 2023. Frac sand is a derivative of deposits of high-purity quartz sandstone containing well-sorted, round, or angular, and durable sand grains. Mining companies extract frac sand, also known as industrial sand or silica sand, by locating and mining sand deposits rich in silica suitable for hydraulic fracturing.
Frack "sand" is actually tiny pieces of quartz- silicon dioxide (SiO2) also known as silica sand. It is not garden variety sand found in your kids sandbox.
