Key Differences
In the process of roasting, ore is heated above its melting point in the presence of air or oxygen while in calcination, ore is heated above its melting point in the absence of air or very limited amount of oxygen supply.
Roasting is mostly done for sulfide minerals while calcination is mostly applied in decomposition of carbonate ores.
Roasting is not used for dehydrating an ore while calcination can be used to drive out moisture from an ore.
In roasting, sulfur dioxide is released while in calcination carbon dioxide is released
