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.
The silica sand is used to make high-end glass, so there is a high requirement for its purity that the content of Fe2O3 is below 90ppm. In order to achieve this effect, after lots of tests and technical exchange, we designed a set of process scheme of grinding and coarse-to-fine magnetic separation. The raw ores contain 0.06 Fe2O3 600ppm.

Sand used in the petroleum industry has been produced in Wisconsin for over 40 years. In recent years, however, the demand for industrial sand has increased exponentially. This growth in industrial sand mining can be attributed to the oil and gas extraction technique known as hydraulic fracturing which relies on silica sand.
Frac Sand Mining. Hydraulic fracturing uses high pressure water to break open underground geologic formations most commonly shale. containing oil and gas. Once the shale is fractured, if the fractures are not propped open, they will close again. So frackers use frack sand to prop open the fractures to allow the oil and gas to be extracted.
