Industrial Sand is ageneral term for high purity silica sand products with controlled sizing. Silica is the name given to the minerals composed of silicon and oxygen. Silica is mostly found in crystalline state but can also be found in the amorphous state as a result of weathering and plankton fossilization.
Uses of Industrial Sand
Industrial sand can be used for a large variety of purposes. Some of them are:
- Metal Production: The industrial sand plays a major role in the production of huge variety of ferrous and nonferrous metals. Silica sand is extremely important in metal production as it works as a catalyst and lowers the melting point and viscosity of slags that makes it more reactive and efficient. Silica is also used to achieve the right base/acid ratio required for purification of metal. Also, steel and foundry industries use silica for the purpose of de-oxidation and refinement.
- Construction: Industrial sand is the primary componentof a wide variety of construction projects. Whole grain silica is used in mortars, flooring compounds, cements, asphalt mixtures, roof shingles etc. to provide flexural strength and packing density without affecting the chemical properties of the binding systems. It also adds durability and anti-corrosive properties to epoxy based compounds.
- Filtration and Water Production: Industrial sand is used for filtration of drinking water, producing water from wells and for the processing of waste water. The industrial sand works as a primary filtration bed and removes impurities and contaminants from both drinking water and waste water. Silica is chemically inert and does not degrade or react when it comes in contact with acids, contaminants, solvents or volatile organics.
- Glass making: Silica sand is the primary component of all types of specialty and standard glasses. Silica’s chemical purity is the primary determinant of glass’s colour, quality and strength.
- Ceramics and Refractories: Ceramic products’ glaze and body formulations require silica as their primary component. All type of ceramics like floor and wall tiles, tableware, sanitary ware etc. require industrial sand as their primary component.
Apart from the above mentioned uses, industrial sand also serves as the primary component in oil and gas recovery, paints and coatings, chemical production and a lot more.
