Uses:-in a powdered form, calcite often has an extremely white color. Powdered calcite is often used as a white pigment or "whiting". Some of the earliest paints were made with calcite. It is a primary ingredient in whitewash and it is used as an inert coloring ingredient of paint. Pulverized limestone and marble are often used as a dietary supplement in animal feed. Chickens that produce eggs and cattle that produce milk need to consume a calcium-rich diet. Small amounts of calcium carbonate are often added to their feeds to enhance their calcium intake. Calcite has a hardness of three on the mohs scale and that makes it suitable as a low-hardness abrasive. It is softer than the stone, porcelain and plastic surfaces found in kitchens and bathrooms but more durable than dried food and other debris that people want to remove. Its low hardness makes it an effective cleaning agent that does not damage the surface being cleaned. Pulverized limestone is also used as a mine safety dust. This is a nonflammable dust that is sprayed onto the walls and roofs of underground coal mines to reduce the amount of coal dust in the air (which can be an explosion hazard). The mine safety dust adheres to the wall of the mine and immobilizes the coal dust. Its white color aids in illumination of the mine. It is the perfect material for this use.

Uses its commercial importance so far electrical industries are concerned. Due to its dielectric properties and low power factor, it is invaluable in electrical industry. it can also withstand with high temperature. Mica films as such are also used in radio valves etc. a number of products like mica tube, mica cloth, mica paper, mica silk, mica tape are manufactured for use in electrical appliances. mica bricks are also manufactured, also used in steel industry as light weight insulating bricks. mica powder used as filler in rubber, as flaxy extender in paints, as in electrode coating and for water proof packing and roofing material. also used in oil drilling, in capacitors, ignition systems, non electrical uses, diaphragm for oxygen breathing equipment, for optical instruments etc.

There are three grades of mica flakes which are normally used for specific purposes: coarse mica flakes: it is used in the manufacture of pearlescent pigments (pearl luster pigments) which consists of natural mica flakes coated with titanium dioxide andor iron oxide. It is also used also to manufacture wet ground mica powder and mica paper. This is available in three grades i.e. A, b and c medium mica flakes: it is effectively used in water-based oil well drilling operations as a mud additive chemical to prevent loss of circulation and seepage in loose formations fine mica flakes: suitable for use when a sealing agent is needed to be small enough to pass through a shaker screen without interfering with the operations. Widely used in manufacturing gypsum board, calcium silicate board and also used as a concrete block filler. High quality white mica flakes are used for bright and artificial snow impression, refractory bricks, asphalt roofing felts, metals explosives and disinfectant etc.

Mica after extraction from the mines is sorted out and the pieces having area larger than 1" sq. And up and a having a thickness of 7 mils and up are classified separately as mica blocks. This mica is the basic raw material for all the various types available for export apart from mica scrap, flakes and powder. These pieces after undergoing size and quality classification as defined in other pages are exported. Mica blocks are irregular in shape.

Uses:- dolomite as a mineral has very few uses. However, dolostone has an enormous number of uses because it occurs in deposits that are large enough to mine. The most common use for dolostone is in the construction industry. It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap or fill. It is also calcined in the production of cement and cut into blocks of specific size known as "dimension stone". Dolomite's reaction with acid also makes it useful. It is used for acid neutralization in the chemical industry, in stream restoration projects and as a soil conditioner. Dolomite is used as a source of magnesia (mgo), a feed additive for livestock, a sintering agent and flux in metal processing and as an ingredient in the production of glass, bricks and ceramics. Dolomite serves as the host rock for many lead, zinc and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite which causes a drop in ph that triggers the precipitation of metals from solution. Dolomite also serves as an oil and gas reservoir rock. During the conversion of calcite to dolomite a volume reduction occurs. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling.

In its altered metakaolin form, as a base component for geopolymer compounds as a component of quik-clot combat gauze, a special gauze preparation designed to stop bleeding from extensive wounds
