Silica sand is the industrial sand and because of the influence of water and wind, quartz over time turns into Silica sand gradually. When gradually it breaks into tiny granules you have to use it and this sand is actually a type of high purity quality Silica Sand products and it is not like common gravels and concrete.

Complex chemical and physical processes are required to ensure that silicon crystals meet the high production standards that apply to chips to convert silica sand to silicon. The sand is combined with carbon and heated to an extremely high temperature to remove the oxygen. Several other steps are required to create the finished product, namely

An estimated 2 million construction workers in the United States have been exposed to respirable silica dust, according to the Occupational Safety and Health Administration. That’s why OSHA’s Respirable Crystalline Silica standard requires that employers limit workers’ exposure to silica and take other steps to protect workers. “Silica dust appears in asphalt, concrete and rocks,” […]
