Chromite ore beneficiation - Idaho Research Foundation, Inc.

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.

Mineralogical characterisation of chromite in the UG2 Reef ...

During the beneficiation of chromite hosted PGE’s by froth flotation, chromite represents the principal gangue mineral. This is particularly true for the UG2 main seam. An excess of more than 3% in mass of chromite in the PGM concentrate is known to result in significant problems in the downstream processing and extraction of PGEs.
