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

The Ordovician St. Peter Sandstone in the Midwest is a primary source of silica sand for many end uses and is a major source of frac sand as well. Mined in five States, frac sand from the St. Peter Sandstone is within reasonable transport distance to numerous underground shale formations producing natural gas.

Extraction of Silica from Rice Husk 72 D. Proposed Process This is new process, silica is manufactured by using rice husk ash as a source of silicate or silica and this ash is then reacted with sodium hydroxide which yields the sodium silicate, which on further reacting with sulphuric acid gives silica along with by-product sodium sulphate.

After extracting silica sand, seeds of plants that grow naturally in that area are sowed into the soil to return the site over a 3 to 4 year period to a mountain of greenery, complete with trees and other natural vegetation. All of the water that is used to purify silica sand is reused.

Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation. Sand mining is a direct cause of erosion, and impacts the local wildlife.
