What is the usage of calcium carbonate?

A. Manufacture of glass. Glass production materials are limestone, quartz sand, soda ash, etc., these materials can be obtained after high temperature melting.

B. Refining steel. In industrial production, limestone is iron melting solvent and runner; the use of quicklime can be used as slagging materials, filter out sulfur, phosphorus.

C. Filling materials for rubber, plastic, paper, cosmetics, toothpaste and other products. After firing it becomes a pure, dry powdered calcium carbonate, which can be used as filler for many products.

D. Manufacture of soda ash. Soda is obtained from limestone, salt, ammonia and other materials by using Solvard method, after a multi-step reaction and the chemical reaction of pure lime and chlorine to achieve bleaching.

E. Making salt. Limestone after chemical processing can become calcium chloride, calcium nitrate, calcium sulfite and other calcium salts.

F. Hard water softener. The hydrated lime can be temporarily reduce the hardness of water, and thus is used as a hard water softener in the industry.

G. Desiccant and disinfectant.

H. Application in Agriculture. First, the lime can be configured as Bordeaux liquid, lime sulfur mixture and other pesticides; Secondly, hydrated lime can change the soil pH, improve the internal composition of soil, add calcium in the soil; then, lime slurry can be used to paint the trunk, protect the trees.

I. Building houses and decorations. Limestone is the main raw material for making cement. In addition, limestone can be used to build the external walls of the house and the ground.
