Difference Between Calcination and Roasting

The key difference between Roasting and Calcination is given below:

Calcination	Roasting
When a material is heated in a limited supply of oxygen then it is known as the calcination process.	When a material is heated with an excess amount of oxygen then this process is known as roasting.
In the calcination process, the removal of water takes place.	In the roasting process, the removal of water does not take place.
Carbon dioxide is emitted during the reaction.	Sulfur Dioxide is released during this reaction.

Calcination

Calcination refers to a thermal treatment process applied to ores and other solid materials in the absence of oxygen or air. Calcination is one of the important methods used for the extraction of metals in metallurgy. This process is carried out in a controlled environment with a regulated temperature. The calcination method generally removes moisture from compounds.

In this article, we are going to discuss the Calcination process, Calcination definition, Calcination formula, Calcination example, the difference between calcination and roasting, and a few applications of calcination.
