Not all silica sands can be used for hydrofracking To meet the industry specifications, frac sand needs to be nearly pure quartz, very well rounded, and must meet tight size gradation standards The sand must also have a high compressive strength, generally between 6,000 psi and 14,000 psi Sands that meet these specifications are mined from How do we get silicon from the earth? The basic process heats silica and coke in a submerged electric arc furnace to high temperatures High temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon This is known as a reduction process In this process, metal carbides usually form first []Can Silicon Be Mined Directly From Earth? CeramicsSilica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust Silica is found commonly in the crystalline state and rarely in (PDF) Geological Overview of White silica Sands
