Silica sand - Business Opportunities

- 2. What Is Silica Sand? • Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). • Regular sand, also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. • These ‘impurities’ make regular sand more chemically reactive and often darker in colour when compared to silica sand. The color for non-silica sands (regular sands) can be various shades white, pink, green, and black as well – depending on the geological makeup and geographic location of the sand deposit.
- 7. Metal Casting: Industrial sand is an essential part of the ferrous and non- ferrous foundry industry. Metal parts ranging from engine blocks to sink faucets are cast in a sand and clay mold to produce the external shape, with a resin bonded core creating the desired internal shape. Silica’s high fusion point (1760°C) and low rate of thermal expansion produce stable cores and molds compatible with all pouring temperatures and alloy systems. Its chemical purity also helps prevent interaction with catalysts or curing rate of chemical binders. Following the casting process, core sand can be thermally or mechanically recycled to produce new cores or molds.
- 8. Ceramics & Refractories: Ground silica is an essential component of the glaze and body formulations of all types of ceramic products, including tableware, sanitary ware, and floor and wall tile. In the ceramic body, silica is the skeletal structure upon which clays and flux components attach. The SiO2 contribution is used to modify thermal expansion, regulate drying and shrinkage, and improve structural integrity and appearance. Silica products are also used as the primary aggregate in both shape and monolithic type refractories to provide high temperature resistance to acidic attack in industrial furnaces.
- 9. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing.
- 10. Construction: Industrial sand is the primary structural component in a wide variety of building and construction products. Whole grain silica is put to use in flooring compounds, mortars, specialty cements, stucco, roofing shingles, skid resistant surfaces, and asphalt mixtures to provide packing density and flexural strength without adversely affecting the chemical properties of the binding system. Ground silica performs as a functional extender to add durability and anti-corrosion and weathering properties in epoxy-based compounds, sealants, and caulks.
- 11. Oil and Gas Recovery: Known commonly as proppant, or “frac sand,” industrial sand is pumped down holes in deep well applications to prop open rock fissures and increase the flow rate of natural gas or oil. In this specialized application, round, whole grain deposits are used to maximize permeability and prevent formation cuttings from entering the well bore. Silica’s hardness and its overall structural integrity combine to deliver the required crush resistance of the high pressures present in wells up to 2,450 metres deep. Its chemical purity is required to resist chemical attack in corrosive environments.
- 12. There are several main uses of silica sand as given below: Metal Casting For Glassmaking Metal Production Paint and Coating Construction Oil and Gas Recovery Filtration and Water Production
- 14. Silica Sand Mining projects
- 15. Key in the real estate construction industry -silica sand screening machine
- 16. New technology silica sand processing equipment
- 17. Screw Sand Washing Machine for Silica Sand, River Spiral sand washing machine is designed to provide bigger capacity and higher cleaning level than traditional one. It is also called “stone washing machine” as its input material size is at most 30mm. Now it is widely used for cleaning materials in quarry, minerals, building materials, transportation, chemical industry, water conservancy and hydropower, cement mixture station and so on.
- 18. Sand Processing
- 19. Silica Sand Beneficiation Plant Capacity:95 tons per hour Silica sand beneficiation plant equipment is used to remove the raw material of iron and other magnetic materials, commonly used in ceramics, mining, chemical, milling and other industries. For example, in the mining industry, the first use of raw materials are generally medium-sized magnetic separator roughing, roughing after the raw material iron content is reduced to a certain extent, it can be used for some of the iron content of less demanding industries. In the iron content of the requirements of the occasion, you need to use the raw crude iron machine after the election will be featured in addition to iron, iron or even several times in order to meet the requirements. Can also be understood as a small addition to iron magnetic separator, usually in raw material handling capacity is not the case, the device is the use of iron.
- 20. Sand Mining Regulations • The prospecting mining operation should be under licence or lease • The supreme court of India ruled that approval under the 2006 environment impact assessment (EIA) notification is needed for all the sand miners collection activity, even if the area being is less than 5 hectares. • There is a need for seeking permission from State Government for the operative mechanism of section 4(A)(1) of MMDRA, 1957. • According to a report on ABC Foreign Correspondents, India sand business employs over 35 million people and is valued at well over $126 billion per annum. The supply problem could partially be attributed to the environmental limitations imposed to protect ecosystem or due to the existence of illegal means to create a supply chain.
- 21. There are various laws in the country to regulate illegal sand mining.
- 22. PERMITS
- 23. Singapore is the biggest importer Singapore is the world’s largest importer of sand, owing to its land reclamation activities which have seen the city-state’s land area increase by 20% in 40 years. Singapore had traditionally used sand from neighboring states, before using up the resource and turning to importing from Malaysia, Vietnam, Indonesia and other Southeast Asian countries. Export of Indonesian sand to expand the land area of Singapore has put at least 80 of Indonesia’s 17,508 islands at risk of disappearance due to sand extraction . Owing to the economic and environmental burden Singapore’s sand imports placed on these countries, nations including Cambodia, Malaysia and Vietnam have since moved to ban exports to Singapore entirely.
