Calcination - Wikipedia

Calcination refers to heating a solid chemical compound to high temperatures in absence or limited supply air or oxygen generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use which is to remove carbon from limestone through combustion to yield calcium oxide. This calcination reaction is CaCO3 → CaO + CO2. Calcium oxide is a crucial ingredient in modern cement and is ...

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking impurities such as nitrogen silicon phosphorus sulfur and excess carbon are removed from the sourced iron and alloying elements such as manganese nickel chromium carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained impurities in the steel is also important to ensure the quality of the products cast from the liquid steel
