Calcination Is The Process Of Heating The Ore

Calcination in simple words can be described as a process of heating some solid material or a substance in a controlled environment. Usually in the process the temperature is also regulated. Calcination is done to bring about some change in the substance physical or chemical constitution. During calcination solids are heated at high temperatures.
