Limestone & Dolomite

useful for

Lime Manufacturing

hydrated-lime-powder- Raj Associates Lime Manufacturer & mining Katni
Limestone and Dolomite are the basic raw material for the manufacturing of Calcine Lime and Dolomatic Lime respectively. When heated with coal it remove carbon di oxide and form Calcium Oxide
CaCO3(s) limestone → CaO(s) lime + CO2(g) carbon dioxide

Cement Industry

Applications of Lime - Cement industry
Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.
High purity lime stone minimize the use of gypsum in cement

Flue Gas Treatment

Applications of Lime - fule-treatment
Limestone is the key agent in the elimination of pollutants from fuel-gas streams of coal-fired power plants, incinerators, and industrial facilities. It is used for a treatment of flue gases before it is released to the atmosphere. This process is called Flue-gas desulfurization (FGD)

Steel Industry

Applications of Lime - Steel industry
Typically, chemical grade limestone is put to use in four iron making processes: Blast Furnace – Chemical grade limestone is utilized to produce the slag which removes impurities from the iron ore reduction process to make the liquid pig iron.
Limestone will react with the temperature in the blast furnace as it continues down the furnace to react with sulfur from the iron and produce a slag with the silica formed from the iron ore. The first reaction involved is as follows: CaCO3 = CaO + CO2 The CaO is used to remove the sulfur and react with the silica to produce a fluid slag at the bottom of the furnace.

Burnt Lime/Quick Lime & Other Lime products

useful for

Aluminium & Copper Industry

Applications of Lime - Aluminum industry
In the mining industry, lime products are used to refine and condition metal ores and non-ferrous metals such as Copper, Zinc, Nickel, Gold, Silver, and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel, and Zinc and are used in Gold and Silver Processing to ensure proper pH in the leaching circuit. They are also used in Aluminum processing to precipitate impurities and regenerate caustic.

Steel Industry

Applications of Lime - Steel industry
Lime can be also used to remove slag in steel pants. Some steel industries directly use Lime instead of Limestone. The CaO is used to remove the sulfur and react with the silica to produce a fluid slag at the bottom of the furnace.

Paper Industry

Applications of Lime - Paper industry
Lime is a primary raw material for paper and pulp industry. Both Quick Lime and Hydrated Lime are essentially required for the manufacturing of pulp and paper in order to enhance the quality of paper by maximizing its opacity.


Applications of Lime - Chemical-industry
Lime contributes to a great deal in the chemical industries. Sigma’s premium products pride and pearl have found application in manufacturing of fine chemicals.

Water treatment

Applications of Lime - water treatment
Lime is extensively used to treat municipal waste waters and industrial liquid wastes. In wastewater treatment plants (both urban or industrial) Hydrated Lime and Quick Lime are widely used for correcting the pH balance of acidic water, for precipitating heavy metals and phosphates, and for its flocculating action.


Applications of Lime - paint industry
All precipitated calcium carbonate, widely employed as a paint pigment, is derived from the lime. It is also used in the manufacturing of cement paints and is used as filler as well.

Sugar Industry

Applications of Lime - sugar-industry
Hydrated Lime and Quick Lime are essential to the production of sugar from both sugar cane and sugar beet. It is used for removal of dirt, puma and pH correction.

Dairy Industry

Applications of Lime - milk-dairies
Lime is one of the alkalis employed to neutralize the acidity in the cream before pasteurization. The addition of lime in the fermented skimmed milk forms calcium lactate, which is marketed as a medicine or further acidified to manufacture lactic acid.

Agricultural Use

Applications of Lime - Agriculture
Lime is popularly used to increase the soil pH level and increase the crop yield. It is also used to improve the physical structure of the soil by reducing surface crusting. It is also used for soil liming, compost, disposal of animal products, fertilizers etc.

Leather Industry

Applications of Lime - leather
Since time immemorial lime has been used for detailing and plumping hides preparatory to leather tanning. A cleaning agent in the leather manufacture process, lime is used to remove raw skin and thus obtain clean leather.

Glass Industry

Applications of Lime - glass-industry
Limestone and lime are the fluxing materials for glass. There is no substitute for liming materials in a glass when color is important.


Applications of Lime - Lubricant-over-gears- Raj Associates Lime Manufacturer & mining Katni
Used during Plastic extrusion as a lubricant in petroleum refining and also lubricating grease manufacturing process.

Pharmaceutical Industry

Applications of Lime - Pharmaceutical-industry Raj Associates Lime Manufacturer & mining Katni
Lime is widely used in the manufacturing of most calcium- based pharmaceuticals.

Construction Industry

Applications of Lime - construccion-raj-associatesRaj Associates Lime Manufacturer & mining Katni
As a building material lime is one of the oldest- probably only antedated by stone and mud. Lime has long been used in the construction industry to make mortar and plaster, serving as a binder in these substances.


Applications of Lime - whitewash
Limewash is a traditional form of paint, used for the internal decoration of buildings with solid walls but without damp-proof courses. The moisture content of such walls is frequently high and varies with the seasons, meaning any wall decoration has to be porous.

Fly-ash bricks industries

Applications of Lime - Fly-ash-bricks-industries-raj-associates
Lime and Lime products are used for manufacturing of Fly Ash Bricks as a substitute for the cement to reduce the cost of bricks.

Aerated Concrete Blocks

Applications of Lime - aerated-concrete-aac-block Raj Associates Lime Manufacturer & mining Katni
Quicklime is mixed with cement, sand, water and aluminum powder to give a slurry which rises and sets to form honeycomb structured blocks which have excellent thermal and sound insulation properties.
