Industrial sand and gravel, often called silica, silica sand, and quartz sand, includes sands and gravels with high silicon dioxide SiO2 content. These sands are used in glassmaking for foundry, abrasive, and hydraulic fracturing frac applications and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are
For more information on sand and gravel mining in Minnesota, contact the Minnesota Department of Natural Resources. For answers to health questions about silica sand exposure, contact James Jacobus at the Minnesota Department of Health, 651-201-4917 or james.jacobusstate.mn.us.
The main use of silica is for flat and container glass manufacture, with 60 of each glass batch being silica sand. Silica sand is bonded with synthetic resins to make moulds and cores for casting metals in metal foundries. In oil drilling, well-rounded sand is used to prop open fissures in reservoir rocks to improve permeability.
benefits of frac sand mining as they pertain to air quality, water quantity, water quality, and reclaiming mines after mining is completed.

Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements silica and oxygen. Specifically, silica sand is made up of silicon dioxide SiO2. The most common form of SiO2 is quartz a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...
Silica. Also called silica sand or quartz sand, silica is silicon dioxide SiO 2. Silicon compounds are the most significant component of the Earths 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.
