Hello everyone...
Although the final outcome of roasting and calcination is the same, they are two different processes used to obtain metals from metal ores. The final outcome of the two processes is the conversion of an ore into an oxide ore. 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 involves the heating of ore in the presence of excess air or oxygen whereas calcination involves the heating of ore in the presence of limited air or oxygen.
Hope this helps you...

calcination is the process where reaction are taken place in absence of air
and here small molecules like H2O ,SO2, CO2 etc are evolved and no chemical change take place
ROASTING is the process where reaction are taken place in presence of air
here chemical change take place during this process oxidation, chlorination etc reaction occur...
