Calcination
Roasting: Calcination is the process in which the ore of the metal is heated to high temperature in the absence or limited supply of air or oxygen. Roasting is the process in which the ore is heated to high temperatures in the presence of excess supply of air or oxygen. Calcination consists of thermal decomposition of calcium ores.
