Air Quality: Respirable Crystalline Silica from Sand Mining

May 07, 2021· Air Quality: Respirable Crystalline Silica from Sand Mining Sand mining is not a new practice in Wisconsin. The recent demand for high-quality quartz sand for a natural gas drilling process called hydraulic fracturing (also known as "fracking" or "frac'ing"), however, has greatly increased this activity – especially in Western Wisconsin.

Silica - Department for Energy and Mining

Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone.As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.

Silica (Frac) Sand Mining - Minnesota Issues Resources Guides

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.
