Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable.Calcination, therefore, is sometimes considered a process of purification. Alternatively, calcination in swirling flow is an energy-saving option. Answer of The process of calcination is used for. Rotary kiln calcination process Rotary kiln refers to rotary calcination kiln (commonly known as rotary kiln) and belongs to the category of building materials equipment. Calcination of diatomite is an expensive process frequently resulting in products with unpredictable structure. Calcination process is used to convert carbonate ores to oxide and release of carbon dioxide gas. Calcination refers to heating a solid to high temperatures in air or oxygen, generally for the purpose of removing impurities or volatile substances. Calcination: Roasting: It is the process of heating the ore to a high temperature in the absence of air, or where air does not take part in the reaction. Al 2 O 3.2H 2 O → Al 2 O 3 + 2H 2 O.
