The specifications for each use vary, but silica resources for most uses are abundant. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.

Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
