In the United States for instance, silica sand production increased from to metric tons from 1996 to 1997 and out of this about 37% is used for glass making while 23% was used as foundry sand. Other uses were hydraulics fracturing (6%) and abrasive (5%) (Bourne, 1994; Wallace, 1997; Langer, 2003).The US produces 30% of the world total silica sand from more than 150 operations and ...
For it to become adequate to process food, Silica (SiO2) is reduced to silicon metal by coke in an arc furnace, to produce the Si precursor of the other chemical processes. The chemical process and production is dependent on the use of industrial sand. As with other industries' use of industrial sand, the importance of silica as a component of chemicals is in the variety of appliions.
