Silica Sand
Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Granules of Minerals or Rocks broken down technically between about one-sixteenth of a millimeter to two millimeters in diameter, falling between silt and gravel in the spectrum of sizes. Mineral quartz over the years, through the work of water and wind has been broken into tiny granules and these granules can be used for many different purposes, and can be found in most non-tropical regions of the world. There are many varieties of sand in the world, each with their own unique composition and qualities.

  • Uses
  • Few thousand years ago crystalline silica was using for some industrial application related to metallurgical and glass making activities. Throughout the history it has played a key role being a raw material in industrial revolution especially in the glass, foundry and ceramic industry. In present time Silica contributes to information technology revolution as it is used in the plastics of computer mouse and also the raw material for silicon chips. For industrial use, pure deposits of silica sand capable of yielding products of at least 95% silica are required. Closely sized Silica sand is the principle filtration medium used for water purification, manufacturing of glass and glass products. Silica has a high melting point, 1610 degrees C. This enables castings to be produced by pouring molten metal into moulds made out of silica sand. Silica that has been ground to fine size is an ingredient of most clay bodies and is a major constituent of ceramic refractories, pottery glazes, and enamel. Typical everyday products include tableware, sanitary ware, ornaments and wall and floor tiles. The construction industry is founded on silica and there are a host of specialist applications including silica and aerated concrete blocks, floor and roof tiles, flooring and rendering compounds, white line markings, roofing felt and cement and resin injection systems. Silica sand is used for equestrian surfaces, in artificial turf, golf course root zones and dressings, football and cricket and other pitches and as play sands. 150 mesh size Silica sand is used in Sawing stone, grinding and surfacing glass and polishing marble Rounded Grains of silica sand are used for sand blasting it is also used as a filler in paints 'Wood Paste' molded hard rubber goods, gypsum Plasters, oxychloride acoustic plasters and soap. Silica has many other applications including the manufacture of chemicals and metals, fillers in numerous products, plastic and otherwise, the manufacture of refractories, stimulating oil production and as additives in agricultural and horticultural products. It is difficult to imagine a life without silica!
  • Production of silica sand
  • Usually below thin layer of soil high grade silica sand is found as unconsolidated deposits. Before sale the sand undergoes considerable process after quarrying it may include washing and cleaning of the grains, sizing to remove coarse and very fine fractions, and physical and chemical processes to remove iron, chromium and other deleterious minerals. After processing, the sand may be dried and some applications require it to be ground in ball mills to produce very fine material.
