view moreThe most significant silica mines are the Glenshera sand pit near Mount Compass, 50 km south of Adelaide, and the 23-Mile lump silica deposit near Whyalla. 2013 production of glass and foundry sand was 476,000 tonne, dominantly from the Glenshera mine area. Production of crushed quartz from the 23-Mile quarry was estimated at 26,000 tonne.

view moreSilica 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. Minnesota is not currently fracking for oil and gas ...
view moreMining, treating, and shipping frac sand have destructive effects on rural communities and natural landscapes. To extract silica, mining companies level bluffs and hills, replacing them with massive holes 100 feet deep. The purest silica is then isolated, which involves washing the sand with millions of gallons of chemical-laced water.
