Calcination is not typically done in a blast furnace.
The process of calcination involves heating solid materials, such as ores, below their melting point in the absence or limited supply of air.
This is done to induce thermal decomposition, remove volatile fractions, or cause phase transitions.
Calcination is commonly carried out in furnaces such as muffle, reverberatory, or shaft furnaces or kilns.
Blast furnaces, on the other hand, are primarily used for the smelting of iron ore to produce iron.
They operate at very high temperatures and involve the reduction of iron ore using carbon monoxide and coke as reducing agents.
The primary purpose of a blast furnace is to extract iron from its ore, not to undergo calcination.
Therefore, while calcination may be performed in various types of furnaces, including muffle, reverberatory, or shaft furnaces, it is not typically done in a blast furnace.
