Calcination and Roasting: An Overview and Explanation
The conversion takes place through a calcination or roasting process. It is easy to reduce oxide ores. However, the ores heat in the absence of oxygen in the calcination process. The entire process becomes vain in the presence of air or oxygen. Oxide ore is reduced in the reduction process. Let’s have closer look at the calcination and roasting process and discuss some important questions.

Calcination
Calcination refers to heating (thermal treatment of) a solid chemical compound (e.g. carbonate ores) to high temperatures in absence or limited supply air or oxygen (O 2), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition.

Difference Between Roasting and Calcination | Definition
Roasting is the process of heating the ore in the presence of air. It involves gas-solid reactions that take place at very high temperatures. Calcination is heating to high temperatures in air or oxygen. However, the amount of air or oxygen here is limited. Therefore, the main difference between roasting and calcination is that roasting
