Abstract
A new process has been developed to extract magnesium from aluminosilicate slags which have high basicity ratios. The process is dependent on the effective utilization of the characteristics of transferred-arc gas plasmas and has important advantages over alternative pyrometallurgical methods of magnesium production. The need for careful control of an invariant slag composition is eliminated, as is the requirement of a vacuum condenser or complex gas quench technology. Significantly improved magnesium yields, when combined with highly efficient usage of the reductant, will greatly enhance the economics of the pyrometallurgical route to magnesium.
