A comparative study on the separating methods of Al,Ca and Mg based on theoretical energy consumption

Based on thermodynamics and physical chemistry theory, the theoretical energy consumption (TEC) of the typical separating processes of Al, Ca and Mg has been calculated and analyzed. This paper attempts to prove that the thermal method is more reasonable than the electrolytic methods to separate Al, Ca and Mg under the domestic circumstances of the low efficiency of coal-firing power plant at present.
