What is Silica Sand?

Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.

Silica The Canadian Encyclopedia

2006-2-7  Silica sand is used as a metallurgical flux to lower the melting point in the base metal industry; as foundry sand for metal castings; as frac-sand to increase porosity and thus increase oil and gas recovery; as an abrasive for sandblasting; and as filler material in tile, asbestos pipe, concrete and bricks. Silica deposits occur throughout Canada.

Silica Sand Mining EIS Meeting - Wisconsin DNR

2012-6-2  Not all silica sands can be used for hydrofracking. To meet the industry specifications, frac sand needs to be nearly pure quartz, very well rounded, and must meet tight size gradation standards. The sand must also have a high compressive strength, generally between 6,000 psi and 14,000 psi. Sands that meet these specifications are mined from

Silica The Canadian Encyclopedia

2006-2-7  Silica. Silica, or silicon dioxide (SiO 2), occurs as the MINERAL quartz and is the most abundant mineral of the Earth's crust. It also occurs in the skeletal parts of some animals (eg, certain protozoa) and various plants. Quartz forms hexagonal crystals and melts at 1723°C; it has a low thermal coefficient of expansion and is very resistant to weathering.
