    Frac sand (“raw frac sand”) is an industrial mineral commodity that consists of a naturally occurring, highly pure silica sand that is used as a proppant during hydraulic fracturing of unconventional oil and gas reservoirs to maximize and extend well production (Beckwith, 2011).

    Silica sand is the major component of glass, foundry molds, and abrasives. It is also used in ceramics, on golf courses, and as a filter medium. In the midwest, the major uses of the sand are in the foundry and automotive industry operations.

    Silica Sand: The primary component of typical beach sand is quartz, or silica (SiO2). Quartz is a hard mineral which, not having any cleavage planes, does not fracture easily. Quartz is found in many types of rocks. Granites, shown below, are common plutonic ...

    Silica sand is a mineral resource. It is mined mostly for glass-making. Another major use of sand is a concrete production but that does not need sand to be as pure. Some beautiful beaches are made of silica sand. Beach of Siesta Key in Florida is especially famous for its white sand. Not all white sands are made of silica, though.

    Demand for silica sand can be segmented into five major markets: glass, foundries, hydraulic fracturing, building products, and chemicals, as well as other smaller markets. Glass is the largest market, accounting for 37 percent of global silica sand consumption (in volume terms) in 2011.

    Silica sand from northern Illinois is famous for its high purity and is widely used in making high-quality glass. Silica sand is also used as molding sand because it can withstand the high temperatures used in casting steel and other metals. It is also used in fracture-treating wells to help increase oil production.

    Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
