Calcined Dolomite

Calcined dolomite refers to dolomite that has been subjected to high-temperature heat treatment, a process known as calcination. Dolomite is a mineral composed of calcium magnesium carbonate (CaMg(CO3)2), and calcination involves heating the dolomite to a high temperature in order to drive off carbon dioxide (CO2) and convert the carbonate minerals into oxides.

The calcination process typically occurs in a rotary kiln, which is a cylindrical furnace. During calcination, the following chemical reactions take place:

  1. Decomposition of Dolomite: CaMg(CO3)2→CaO+MgO+2CO2CaMg(CO3)2→CaO+MgO+2CO2

    The carbon dioxide (CO2) is released as a gas, and the remaining products are calcium oxide (CaO) and magnesium oxide (MgO).

  2. Formation of Quicklime: CaO→CaO+CO2CaO→CaO+CO2

    In this step, any remaining carbon dioxide is released, and the final product is calcium oxide (CaO), also known as quicklime.

The calcined dolomite is used in various industrial applications, including:

  • Steel Production: Calcined dolomite is used as a flux in the production of steel. It reacts with impurities in the iron ore and helps remove them, improving the quality of the steel.

  • Magnesium Production: The calcination of dolomite is also a step in the production of magnesium metal. The magnesium oxide obtained from calcined dolomite can be further processed to extract magnesium.

  • Soil Amendment: Calcined dolomite is used as a soil amendment in agriculture to neutralize acidic soils. It provides calcium and magnesium to the soil, promoting better plant growth.

  • Refractories: Calcined dolomite is used in the production of refractory materials, which are resistant to high temperatures. These materials are used in various industrial processes, such as in the lining of furnaces.
