A process is provided for producing salt-coated spheroidal granules of magnesium by employing a molten flux bath comprised of a salt composition of NaCl, KCl and CaCl.sub.2 maintained at a temperature in excess of the melting point of magnesium to which is added magnesium metal. A magnesium oxide dispersing agent is maintained in said bath in an amount sufficient for dispersing said magnesium. The bath mixture is subjected to high energy stirring sufficient to disperse the magnesium metal throughout the bath as beads. The bath mixture is then rapidly chilled to form a friable mass of the salt composition with spheroidal granules of magnesium dispersed through the salt matrix. The friable mass is then comminuted under conditions to release the magnesium from the salt as salt-coated spheroids which are thereafter recovered.
