Chromite ore beneficiation

Chromite ore beneficiation. Disclosed is a process for beneficiating chromite ore. The process can also be used to remove SO 2 from SO 2 -air mixtures which would ordinarily be vented. The chromite ore is pulverized and preferably mixed with sodium sulfate. Ammonium carbonate can also be added for subsequent vaporization to increase porosity.
