Calcination Wikipedia

Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.

Calcined dolomite | SMA Mineral

By heating the mineral dolomite (CaMg(CO 3) 2). Uses: In steelmaking, both quicklime and calcined dolomite are used as a flux and slag conditioner and to prevent the steel from oxidising. This process also collects impurities that are damaging to the steel. Calcined dolomite also protects the refractory lining of the steel furnace, oxygen converter and ladle furnace. Both products can be
