Frac Sand Sources in the United States The premium frac sand is >99 percent quartz or silica (SiO2) (Zdunczyk, 2007, 2014), although a great deal of sand used as frac sand falls within the range of 9599 percent silica content. Mineralogical purity as to silica content is a characteristic of mature and supermature sand or sandstone, which has been highly reworked and well sorted, so that
Quartz is found in the nature in varying purity and is traded in varying quality for different industrial appliions. It can be used either for high added value appliions such as siliconmetal wafers, optical glass or PV panels or for more ordinary appliions such as foundry sand for metal castings or as a filler for adhesives and grouts.
Silica sand mining Silica sand mining Southeastern and south central Minnesota and southwestern Wisconsin have extensive deposits of sand that meets the specifiions required for hydraulic fracturing, or "fracking," a drilling method used for natural gas and oil wells. Mining of these deposits has been occurring in the region for many
The specifiions for each use vary, but silica resources for most uses are abundant. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.

Sand mining is a largelyoverlooked side effect of the fracking boom. "Frac sand" refers to the fine, white silica or quartz sand that is in high demand for use in hydraulic fracturing. The fracking process involves drilling a well thousands of feet underground, cracking open the shale rock, and
Silica is synonymous with silicon dioxide (SiO2). Silicon and oxygen are the two most abundant elements in the earth's crust. Silica is commonly found in nature as sand. Silica exists in many different forms that can be crystalline as well as noncrystalline (amorphous).
Winona County, Minnesota's only county to ban the mining of silica sand for use by the oil and gas industry in hydraulic fracturing, goes to court Thursday to defend the ban. Minnesota Sands LLC, which holds extensive mineral rights in southeastern Minnesota, is challenging the legality before the
