Magnesite, a compound of magnesium carbonate, is often extracted from dolomite rock. Dolomite rock is a sedimentary rock formation rich in magnesium and calcium. Various processes are used to produce magnesite from dolomite rock, including the latest process of thermal treatment.

The process begins with the mining of dolomite rock in quarries. The recovered rock is then crushed and ground into a fine powder form. This dolomite powder is then placed in special furnaces or reactors where it is subjected to high temperatures.

In the latest process, thermal treatment, the dolomite powder is heated at temperatures of around 700 to 900 degrees Celsius. This temperature activates chemical reactions in the rock and leads to the conversion of dolomite to magnesite. During the heating process, the carbon dioxide is released from the dolomite rock and pure magnesium oxide is formed.

After the thermal treatment is complete, the resulting product, magnesite, is cooled and processed into various shapes and sizes. Depending on the intended use, magnesite can be offered as powder, granules or as pressed plates and shapes.

The thermal treatment process enables the efficient and controlled production of magnesite from dolomite rock. It ensures high purity of the magnesite and allows product quality to be tailored to specific requirements and applications.

The magnesite produced is used in various industries. It is used as a raw material for the manufacture of refractories in the steel industry, as a filler in plastics and coatings, as a component of fertilizers and in many other applications.

The production of magnesite from dolomite rock is continuously optimized through the constant further development of process engineering and the use of the latest technologies. This leads to improved product quality and increased efficiency in production.

Overall, the production of magnesite from dolomite rock is an important process that allows this versatile mineral to be used in various industries and benefit from its unique properties.
