ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing Quartz is very resistant to both chemicals and heat. It is therefore used as a foundry sand. With a melting temperature higher than most metals, it can be used for the molds and cores of common foundry work. Refractory bricks are often made of quartz sand because of its high heat resistance. Quartz sand is also used as a flux in the smelting of metals. Quartz sand has a high resistance to being crushed. In the petroleum industry, sand slurries are forced down oil and gas wells under very high pressures in a process known as hydraulic fracturing . This high pressure fractures the reservoir rocks, and the sandy slurry injects into the fractures. The durable sand grains hold the fractures open after the pressure is released. These open fractures facilitate the flow of natural gas into the well bore Quartz sand is used as a filler in the manufacture of rubber, and putty. Screened and washed, carefully sized quartz grains are used as filter media and roofing granules. Quartz sands are used for traction in the railroad and mining industries. These sands are also used in recreation on golf courses, volleyball courts, baseball fields, children's sand boxes and beaches. It is submitted that there are 02 quarry leases located Saggonda area of Gopalapuram mandal. The production of Quartz from establishment of this office to so far 04 Lakhs tones approximately was excavated and revenue collected 180 Lakhs approximately.
