Beneficiation and mineral processing of magnesium minerals
Mar 29, 2016 High grade magnesite or Caustic Calcined Magnesia (CCM) as raw materials for 12 hours is required for the fusion process at temperatures in excess of 2750 C. The process promotes the growth of very large crystals of Periclase ( 1000 microns) with a density approaching the theoretical maximum of 3.58 g/cm3.
