· Sand mining operations designed to mine and export "frac sand" are often much larger in acreage than the smaller, more traditional Wisconsin sand mines that serve mainly local needs for sand. The sand is desirable for frac''ing and some other uses due to its size, shape, and crystalline silica properties and because the deposits are usually close to the surface and easy to mine.
· Economic Impacts of Industrial Silica Sand (Frac Sand) Mining. Benefits of silica sand mining are often discussed in terms of creating highpaying opportunities for employment, increasing regional economic activity, generating tax revenues for state and local governments, and improving economic diversity in rural communities that rely heavily on agriculture for income.
· This sand is largely composed of noncrystalline amorphous silica (only between .05 and 2% of sharp glasslike crystalline silica is allowed), a substance found in humans, plants, rocks, and sand. Food grade DE is used in toothpaste, skincare products, beverages, foods, and medicines.
· Crystalline silica, found in the earth''s crust, is a basic component of many minerals. Quartz, cristobalite, and tridymite are all forms of crystalline silica that can become inhalable dust when they are cut or ground. This dust is harmful when inhaled, causing .

While silica is not harmful within these materials, it can be deadly when it is breathed in. Respirable crystalline silica is commonly found on jobsites around the world. When employees cut stone or other materials that contain the silica, it is broken down into dust that can be 100 times smaller than a grain of sand.
