how is quartz silica extracted
QA: OSHA Regulations On Concrete Silica Dust
Nasvik: Silicon (Si) is the second most common element on Earth, making up 28% of the planet's crust. Oxygen is the most common element at 47% and aluminum is a distant third at 8%. Silicon combines with oxygen to form quartz (SiO2) — an example being sand. Silica is a component in a wide range of the Earth's rock.

Silica | IMA Europe
The name Silica covers a range of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica exists in ten different crystalline forms. By far the most common of these is quartz. It is hard, chemically inert and has a high melting point. Silica is sold as sand and processed for multiple uses.

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.
