About dolomite, not calcined or sintered; including dolomite roughly trimmed, or merely cut by sawing or otherwise into blocks or slabs of rectangular (including square) shape

HS code 251810 covers dolomite, a naturally occurring mineral composed of calcium magnesium carbonate. Dolomite is a widely used industrial mineral, with applications in construction, metallurgy, and agriculture, among others. As a key input for various industries, the dolomite trade plays an important role in the global economy.

Production process

Dolomite is primarily extracted from quarries and mines through conventional open-pit mining techniques. The raw dolomite is then crushed, screened, and sorted to meet specific size and purity requirements. Depending on the intended use, the dolomite may be further processed, such as by cutting or trimming into blocks or slabs of rectangular shape.

Production inputs

The main inputs for the dolomite industry include the raw dolomite deposits, as well as mining and processing equipment such as excavators, crushers, and saws. Energy sources, such as electricity or diesel fuel, are also required to power the extraction and processing operations. Additionally, labor and transportation infrastructure are essential for the efficient production and distribution of dolomite.

Production outputs

The primary output of the dolomite industry is the processed dolomite material, which is then consumed by various downstream industries. Some of the key consumers of dolomite include the 251820 Dolomite, calcined or sintered industry, the 252100 Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement industry, and the 271500 Coal, lignite and peat industry, where dolomite is used as a flux material.
