Calcination and Roasting Definition, Differences and FAQs
Calcination is done for the Carbonate Ores. In the calcination process, the ores are heated strongly in the absence of oxygen (air). This is done so as to convert the Metal Carbonates into Carbon Dioxide and Metal Oxides. If these ores are heated in the presence of oxygen or air, no reaction will take place, and the entire process will become vain.
