Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday

Our Manufacturing/Mining Process. Nugent''s manufactures silica lake sand with production capacity of over 1,000,000 tons per year.
Silica is a "building block" material that forms rocks, soil, sand, and other parts of the earth. A large amount of the earth is made up of silica. Silica occurs in either a crystalline or an amorphous structure. Over many years, silica in the soil can form into crystalline silica due to natural heat and pressure.
