Chalk and dolomite

CPC v2.1 Code: 1633

About chalk and dolomite

cpc code 1633 covers the extraction and processing of chalk and dolomite, two important industrial minerals with a wide range of applications. Chalk is a soft, white, porous sedimentary rock composed primarily of the mineral calcite, while dolomite is a type of limestone containing significant amounts of the mineral dolomite. These materials are essential raw materials for various industries, including construction, agriculture, and manufacturing, making them an integral part of the broader economy.

Production process

The production of chalk and dolomite typically involves quarrying or mining the raw materials from natural deposits, followed by crushing, screening, and sometimes further processing to meet specific industry requirements. Chalk is often extracted from chalk cliffs or underground chalk deposits, while dolomite is mined from dolomite rock formations. The extracted materials may then undergo additional steps such as washing, sorting, and chemical treatment to refine the product and remove impurities.

Production inputs

The main inputs required for the chalk and dolomite industry include the natural deposits of these minerals, as well as the machinery and equipment needed for extraction, processing, and transportation. This includes excavation equipment, crushers, screens, and other processing equipment. Energy sources, such as electricity or fuel, are also necessary for the various stages of production.

Production outputs

The primary outputs of the chalk and dolomite industry are the refined and processed materials, which are then used as inputs for a wide range of industries. Chalk is commonly used in the production of cement, glass, and ceramics, as well as in the manufacture of paints, plastics, and rubber. Dolomite, on the other hand, is used in the production of steel, glass, and refractory materials, as well as in the agricultural sector as a soil amendment. The outputs of this industry may be consumed by other industries represented by codes such as 2394 Cement, lime and plaster, 2310 Glass and glass products, and 0141 Agricultural and animal husbandry services.
