ABSTRACT A process for extracting magnesium from compounds con- taining magnesium oxides is disclosed, The process is carried out at lower temperatures and pressures than previous processes which does not melt the dross. The process comprises the steps of mixing magnesium oxide and calcium oxide with aluminum, com- pressing the mixture, heating the compressed mixture uniformally to a temperature in the range of 800-1100°C. under controlled pressure to vaporize the magnesium, and condensing the vaporized magnesium on a cooled surface.
