Sand is critical to fracking. After workers drill down into rock, they create fractures by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand.

Silica sand mining business has more than doubled since 2009 because of the need for this particular type of sand for a process known as hydraulic fracturing. Wisconsin is one of the five states that produce nearly 2/3 of the entire nation''s silica.

Also called silica sand or quartz sand, silica is made of 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 .

Industrial sand mining overview. Sand mining has occurred in Wisconsin for more than 100 years. Recent growth in the petroleum industry has created a high demand for sand that can be used for hydraulic fracturing, a technique used to extract natural gas and crude oil from rock formations in .

Mining, treating, and shipping frac sand have destructive effects on rural communities and natural landscapes. To extract silica, mining companies level bluffs and hills, replacing them with massive holes 100 feet deep. The purest silica is then isolated, which involves washing the sand with millions of gallons of chemicallaced water.

Sand mining is a common practice in many rivers and floodplains across South Africa. The demand for sand is escalating at an alarming rate as a result of everincreasing building construction projects and other infrastructural development. This has contributed to in
