We are considered as reliable Manufacturer, Exporter and Supplier of Limestone Lumps in the market. We deal in Limestone, calcium carbonate, precipitated calcium carbonate, ground/pulverized calcium carbonate, PCC, GCC, calcite, limestone, crushed marble, ground limestone, lime, chalk, whiting, champagne chalk, French chalk, albacar, and aeromatt.

Limestone Formula : CaCo3

Limestone Description : Produced by crushing, grinding, precipitation, and classifying high purity, white, calcite limestone.

Limestone Mineralogy :
Limestone ores can be found in two of the three major types of rocks: sedimentary and metamorphic. Sedimentary rocks, as the name suggests, form from sediment or from transported fragments deposited in water. Limestone, for example, is formed from inorganic remains, such as shells and skeletons. Metamorphic rocks-such as marble, slate, quartzite-form when a rock mass is subjected to great heat and pressure. The principal element in the calcium carbonate ore is calcium (Ca). The ore may contain other elements such as Magnesium (Mg), Iron (Fe) and Manganese (Mn)- that affect whiteness, hardness and specific gravity of Limestone.

Limestone Typical Applications :

  • Plastics, rubber, coatings, inks, adhesives, and soil conditioner, building products, plastic filler, ceramic flux, asphalt filler, chemical processing, glass ingredient, water treatment, pesticide granules, dusting agent, welding rods coating, thermosets, thermoplastics, paints, coatings, adhesives, sealants, rubber, pharmaceutical, toothpaste, and food additive.
  • Limestone has a wealth of uses: as a flux in steel production and in processing of non-ferrous metals; in bricks, mortar and concrete for construction; as a raw material in glass; in the construction of roads and dams; in the manufacture of paper, paints and dyes, carpeting and other floor coverings; and in the treatment of water, industrial waste, gases and household refuse. It is also used to reduce soil acidity in agriculture, to absorb water and add calcium in food products, and in sugar extraction.
  • Limestone is a versatile additive for use in a wide range of plastic and elastomeric applications. Its regular and controlled crystalline shape and ultrafine particle size together with the hydrophobic surface coating, combine to the benefit of both polymer processing and subsequent physical properties.


Packaging : 50 Kg bags, poly-lined fiber drums, 1MT bulk bags and loose bulk.
