Technique for the isolation of secondary phases in processed magnesite.

ABSTRACT

The study describes a new wet chemical technique, termed ANM, for the isolation of secondary phases in magnesite processed at a temperature of 1650 degrees C. The major MgO (periclase) phase in processed magnesite was preferentially extracted as ammonium nitrate magnesium double salt by ammonium nitrate in ethanol medium. The residues containing enriched secondary phases were identified by XRD.
