Application of calcium carbonate in industries

Calcium Carbonate Powder in Industries Calcium carbonate powder, precipitated products and dolomite are one of the most important and diverse materials used in the industry. Calcium carbonate has various applications in the industry, which are mentioned in the text below. 1- Calcium carbonate is used in industries to clean and separate iron from ore. 2- It is used in swimming pools to maintain the alkalinity of water and to counteract the acidic properties of disinfectants. 3- Calcium carbonate, because it is heavy, increases the density of drilling fluids and helps in controlling downhole pressure. That is why it is widely used in the oil industry. 4- As a result of the decomposition of calcium carbonate, carbon dioxide and lime are produced, which are used in the glass and steel industries. 5- Calcium carbonate is the most common mineral in the paper industry, which is used to fill and coat paper. 6- It is used as a filler in seals and adhesives. 7- Calcium carbonate is also used in industries in the production of mortar, which is used for making concrete blocks, bonding bricks, rubber compounds, tiles, etc. 8- Calcium carbonate is used in the construction of buildings, roads and other engineering works. It is used in the construction industry as a building material, ceramic tiles and also as a component of cement. 9- It is also used in the chemical and metallurgical industries. 10- It is mainly used in steel production, slag formation and in blast furnaces 11- It is used as blackboard plaster. 12- Coated types of precipitated calcium carbonate are used as rheological modifiers in a wide range of sealants and especially in the formulation of PVC plastic used in the automotive industry. Its use significantly simplifies the design of new formulations due to its easy dispersion, high performance value and low viscosity. 13- Also used in printer inks, the fine particle size of PCC helps to improve various optical and rheological properties of printing inks. 14- Used in lubricants and greases. 15- Tanning is the conversion of any animal hide into leather in a way that results in specific physical, chemical and biological properties. To carry out this process, it is necessary to use acid which must later be neutralized, so both calcium carbonate and dolomite are used.
