Silica Sand Silicon and oxygen are the earth's two most abundant elements and together they make silica, one of the earth's three most common rock forming minerals. Silica occurs in three main crystalline forms. The principal occurrence is as the mineral quartz but it also occurs in other rarer mineral forms known as tridymite and cristobalite. It is a very durable mineral resistant to heat and chemical attack and it is these properties that have made it industrially interesting to man.   The first industrial uses of crystalline silica were probably related to metallurgical and glass making activities a few thousand years BC. It has continued to support human development throughout history, being a key raw material in the industrial revolution especially in the glass, foundry and ceramics industries. Silica contributes to today's information technology revolution being used in the plastics of computer mouses and providing 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. Often much higher purity values are needed.   Uses of Silica Sand The main end uses of silica sand are:   Glass Silica is the major ingredient in virtually all types of glass. The principal glass products include containers (bottles and jars), flat glass (windows, mirrors, vehicle glazing etc.), lighting glass (light bulbs, fluorescent tubes, etc.), tableware (lead crystal, drinking glasses etc.), TV tubes and screens, decorative glass, fibreglass, optical glass and vacuum flasks. Foundry casting 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. Ceramics Silica that has been ground to fine size is an ingredient of most clay bodies and is a major constituent of ceramic glazes. Typical everyday products include tableware, sanitary ware, ornaments and wall and floor tiles. Filtration Closely sized grades of silica sand is the principal filtration medium used by the water industry to extract solids from wastewater. Specialist building applications 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. Sports and leisure 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. Other users 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 High grade silica sand is usually found as unconsolidated deposits below thin layers of soil and overburden. After quarrying, the sand often undergoes considerable processing before sale. The processing 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

Quartz (Silica SiO2) is the most common mineral in the Earths crust. Quartz is found in sandstones, pegmatites granites, and other igneous rocks. It forms veins in the cracks of rocks. There is a lot of heat and water where they form. Crystals are made when the quartz cools down. The way the crystal looks depends on how hot it was when it was formed. It can be found in layers or geodes, too. Geodes are hollow rocks that are lined with crystals. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colors and forms. Of all the minerals, quartz is closest to a pure chemical compound and has constant physical properties.   It is hard, chemically inert and has a high melting point, attributable to the strength of the bonds between the atoms and extremely resistant to weathering. These are prized qualities in applications like foundries and filtration systems. Quartz may be transparent to translucent and has a vitreous luster, hence it is used in glass and ceramics. Quartzs strength, silicon dioxide contribution and non-reactive properties make it an indispensable ingredient in the production of thousands of everyday products.   We supply Quartz in Lumps, grits/Sands and powder forms for various industrial applications:-   Quartz sand/grains in Glass Industry:- Quartz is commonly known as silica sand for producing float glass, fiber glass, automotive glass, clear container glass, Borosil glass and other types. We produce quartz powder for high purity glass having extremely low levels of contaminating metal oxides, and other foreign particles with the help of heavy magnetic separators used in mesh 25 to 32 or in mm size 0.1mm-0.3mm, 0.3mm - 1.2mm, 0.5mm-0.1mm, 1.2mm - 0.3mm. Fused Quartz (Silica glass), vitreous silica glass: silica (SiO2) is used for very special applications and has very low thermal expansion, is very hard and resists high temperatures (1000 1500 C). It is also the most resistant against weathering (alkali ions leaching out of the glass, while staining it). It is used for high temperature applications such as furnace tubes, melting crucibles, Flat glass, Automotive Glass Hollow Glass (e.g. Thermal expansion, hardness, specific gravity).

Marble   Marble is a non-foliated, granular metamorphic rock. That is formed by the metamorphism of limestone and dolostone. In the global market Marble is one of the seven natural stones which have a massive demand. Marble has long been highly valued for its beauty & strength; Marbles are suitable for both interior and exterior applications. Construction marble is a stone which is composed of calcite, dolomite or serpentine which is capable of taking a polish. It adds grace tothe appearance of floors, walls, table tops etc. It radiates an aura of fabulous charm in the ambience of a monument. Marble brings a touch of gleaming charm, prosperity and delight in residential & commercial complexes through its imperial magnificent look.   Marble floor tiles are also used for both interior and exterior flooring applications. Marble tiles are used for bathrooms, entrances and fireplaces, living & dining areas. Some of the different colors of marble are white, red, green, pink, grey, mottled and banded. We are the suppliers & exporter of marble tiles, marble slab, white marble, marble floor tiles. Marble is available in Polished & Tumbled finish.
