Calcium carbonate is the main component of limestone, limestone is the main raw material for glass production. A large number of lime and limestone used as building materials, is also an important raw material in many industries. Calcium carbonate can be directly processed into stone and fired into the quicklime.

Quicklime and slaked lime there. The main component of lime is CaO, general is massive, pure white, pale yellow to pale gray or containing impurities.


Lime to absorb moisture or water becomes slaked lime, hydrated lime, also called slaked lime, its main component is Ca (OH) 2. Slaked lime after deployment into lime slurry, lime paste, lime mortar, used as coating materials and tile adhesives.

Cement is made from limestone and clay mixed, prepared by high temperature calcination. Glass limestone, quartz sand, soda ash (sodium carbonate) and other mixed, high temperature melting system.

Iron with limestone for flux to remove the gangue.

Steelmaking slag material made with lime to remove sulfur, phosphorus and other harmful impurities.

Calcium carbide (main ingredient is CaC2) are lime and coke in an electric furnace in the reaction.

Soda ash is limestone, salt, ammonia and other raw materials obtained through multi-step reaction (Solvay method). The use of lime and caustic soda reaction made (harsh method).

The use of pure lime and chlorine bleaching powder obtained by the reaction.

By chemical processing of limestone into calcium chloride, calcium nitrate, calcium sulfite and calcium important.

Lime can remove the temporary water hardness, it is used as a water softener.

Burn limestone processed into pure powdery calcium carbonate, used rubber, plastics, paper, toothpaste, cosmetics and other filler.

Lime and soda-lime soda made carbon dioxide is used as absorbent.

Quicklime used as a drying agent and disinfectant. Agriculture, with lime formulated mixture of lime sulfur, Bordeaux mixture and other pesticides.

Soil application of lime to neutralize the acidity of the soil, improve soil structure, supply the plant needed calcium.

Stone whitewashed trunks to protect the trees.

Calcium carbonate is an important building material. Pure white calcium carbonate rock called the white marble, can be directly used for decorative columns or crafts.

Due to impurities and has a beautiful pattern is called marble calcium carbonate, used for building facades and veneer wall or laying the ground.

Dense texture of the calcium carbonate rock (limestone) can also be used directly in the building, but the main purpose is the production of limestone cement.

Containing more than 90% CaCO3 with Whitehead Raymond or other high pressure mill grinding, classification, separation, and the obtained product.
