Vermiculite is a mica-like mineral which exfoliates (expands or "pops" upon rapid heating) to produce an inert, low-density material with significant thermal qualities- it does not burn and provides excellent heat resistance. Vermiculite has been used in various industries. It is used in the construction, agricultural, horticultural, and industrial markets.Vermiculite is the mineralogical name given to hydrated laminar magnesium-aluminum-iron silicate which resembles mica in appearance. When subjected to heat vermiculite has the unusual property of exfoliating or expanding into worm-like pieces .This characteristic of exfoliation, the basis for commercial use of the mineral, is the result of the mechanical separation of the layers by the rapid conversion of contained water to steam.The increase in bulk volume of commercial grades is 8 to 12 times, but individualflakes may exfoliate as many as 15 times. There is a color change during expansion that is dependent upon the composition of the vermiculite and furnace temperature. . \USAGES: AGRICULTURAL Animal feed Anti-caking material Bulking agent Pesticide Seed encapsulant Soil conditioner CONSTRUCTION Acoustic finishes Air setting binder Board Fire protection (internal/external) Floor & roof screeds (lightweight Insulating concrete) Gypsum plaster Loft insulation Sound deadening compounds HORTICULTURAL Blocking mixes Hydroponics Micro-propagation Potting mixes Rooting cuttings Seed germination Seedling wedgemix Sowing composts Twin scaling bulbs INDUSTRIAL Absorbent packing Brake pads & brake shoes Castables Dispersions Drilling muds Filtration Fireproof safes Fixation of hazardous material Furnaces Insulation blocks & shapes Insulation - high & low temperature Molten metal insulation Moulded products Nuclear waste disposal

Pyrophyllite belongs to the montmorillonite group of minerals. It is remarkably similar totalc, which belongs to the same mineral family, except that magnesium is substituted foraluminium. In fact, chemical tests are often requires to tell the two apart.pyrophyllite breaks or exfoliates into leaves when fired to temperatures in excess of800°C as a result of dehydration of its structure.StructurePyrophyllite has a sheet-like structure consisting of two silicate layers being sandwichedbetween gibbsite (Al(OH)3) layers Properties of Pyrophyllite   Pyrophyllite is quite soft with a Mohs hardness of 1 to 1.5 and can be scratched witha finger nail   It can be machined to tight tolerances using conventional maching techniques and tools   It is thermally stable up to about 800°C when it will begin to exfoliate   Usages Historically pyrophyllite has been used for carving statues and ornaments owing to its relative ease of machinability. More recently,resistors, transducer cores, high vacuum gaskets and insulators in electron microscopes.Other uses for pyrophyllite are in:   Ceramic formulations e.g. tile and refractory compositions   Plastics and rubber as a filler   Paint   Insecticides Main features : High degree of Absorption, free From silica and others Low bulk                                     density, Very low mositureApplications   : Filler in rubber industry Reinforcing filler against Alumina silicate in rubber Foot                                    wear, General purpose filler , as extended filler in paints          

Feldspar is the most abundant rock-forming mineral in nature & comprises a group of minerals consisting of aluminium silicates with potassium, sodium & calcium & mixture of these elements.

  NATURAL GRAPHITE : Graphite most commonly occurs in metamorphic rocks, such as crystalline limestones, schists and gneisses. It may occur as large crystalline plates. It has probably been derived from carbon material of organic origin which has been converted into graphite during the metamorphism of the rock. Coal beds, under influence or strong metamorphic action, such as the intrusion into them of an igneous rock, have in a greater or less degree been converted into graphitic.USAGES:Because graphite flakes slip over one another, giving it its greasy feel, Graphite has long been used as a lubricant in applications where lubricants, such as oil, can not be used Natural graphite is used in refractory applications. To make Brake Linings, Lubricants and Molds in foundries.

Garnet sand is a mixture of several different minerals and materials. The garnet sand pieces are small, angled and made from many different colors--brown, red, pink. Most pieces in garnet sand are between 8 and 300 micrometers--the smaller the pieces, the less abrasive.  In India, the deposits of Garnet is formed along the coastal Track as Placer deposit. And we have identified the deposits in southern Part of Tamil Nadu in India  along the coastal track of Bay of Bengal. USES : One of the main uses for the sand is a replacement for silica in sand blasting. Garnet sand is often used as a water filtration medium, because it is able to trap small particles of contaminants between the angles of the sand. Garnet sand provides a non-slip surface on walkways and staircases. Garnet sand is used to cut metal when combined with high-pressure water sprays. Some forms of garnet sand are used to make sandpaper. Garnet sand is used for glass and metal polishing.

Fireclay is generally of sedimentary origin. Strictly speaking, fireclay is of sedimentary origin and mainly found in the coal measures, as bedded deposits. A group of refractory clays which can stand temperatures above Pyrometric Cone Equivalent (PCE) 19 are called fireclay. The clay which fuses below PCE 19 is not included under refractory. Fireclay is essentially of kaolinite group and has a composition similar to that of china-clay. In nature it is usually found to contain 24-32 per cent Al2O3, 50-60% SiO2 and LOI between 9 to 12%. Impurities like oxides of calcium, iron, titanium and magnesium and alkalies are invariably present, making it white, grey and black in colour. Like other clays, this clay is highly malleable in raw form. It can be molded, extruded, shaped by hand, and stamped. Various additives can be mixed in to make it more coarse, and it can be ground to be smoother. Slip and scraps for fire clay manufacturing can also be recycled, as long as they are not fired, and worked into new batches of clay for use. Fire clay also shrinks after it has been molded . Refractoriness and plasticity are the two main properties  in fireclay for its suitability in the  USAGES: Raw Material for Refractory Bricks In boiler furnaces Glass melting furnaces Chimney linings Pottery kilnsblast furnaces Reheating furnaces

Stone Form : Block

Brand Name : Guha

Type : Granite

Color : Black

Occurrence ::A mineral of secondary origin, commonly produced under tropical climatic conditions by the prolonged weathering of aluminum-bearing rocks. Also at times derived from the weathering of clay-bearing limestones. It has apparently originates as a colloidal precipitate. It may occur in place as a direct derivative of the original rock or it m ay have been transported and deposited in a sedimentary formation. In the tropics, deposits, known as laterites, consisting largely of aluminum and ferric oxides are found in t the residual soils. These vary widely in composition and purity but may at time become valuable as sources of aluminum and iron. Bauxite is not a mineral, but a rock with minerals in it. Bauxite is a sedimentary rock that is an aluminum ore. It is formed in weathered volcanic rocks. USAGES:Bauxite is used in aluminum Industries , cement, chemicals, face makeup, soda cans, dishwashers, siding for houses, and other aluminum products.  It is recycled so that it can be used over again. MINING: Bauxite consists of 45-60% aluminum oxide, 12-30% water, and various other impurities. Bauxite is typically mined in open-pits and either processed . The water in bauxite is taken out of the ore.  This leaves a white powder that is called alumina which is another name for aluminum oxide.  Alumina is made into aluminum.
