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.
