The key difference between Calcination and Roasting is given below:
|
Calcination vs Roasting |
||
|---|---|---|
| Characteristics | Calcination | Roasting |
| Definition | In this process, an ore is heated in the absence of air. | In this process, an ore is heated in the presence of air |
| Temperature | Moderate | Relatively higher temperature |
| Air or inert gases | Absence of oxygen | Presence of oxygen |
| End Products | Oxides or carbonates | Oxides or sulfides |
| Examples | Conversion of Limestone (CaCO3) to lime (CaO) | Conversion of Copper sulfide (CuFeS2) to copper oxide (Cu2O) |

Calcination and Roasting
Calcination and Roasting are processes used to convert ore into oxide. The difference between the two is the presence or absence of air. Roasting involves heating ores with oxygen below their melting point in the presence of air. Calcination involves heating ore to a high temperature in the absence of air.
In this article, we will understand what is Calcination and Roasting, their examples, and processes, along with a comparison between calcination and roasting.
