Comparison of Extracting Magnesium by Aluminothermic Reduction and Pidgeon Process

Abstract:

The reduction ratio was compared between the Pidgeon process and the aluminothermic reduction process with CA₂, CA, C₁₂A₇ as the main production in the residue. The results of XRD show that the main phase in the reduction residue is CA₂, CA, C₁₂A₇ and Ca₂SiO₄, respectively. Consideration of the efficiency of extracting magnesium, the aluminothermic reduction process which is CA₂ as the main phase in the reduction residue, is the best one.
