  Conversion of Chromium Ore Processing Residue to Chrome Steel

  Conversion of Chromium Ore Processing Residue to Chrome Steel Introduction Chromium played an important role in the industrial development of New Jersey from 1905 to 1971. During that period, chromate (Cr6+) was produced from chromite ore at three facilities in Hudson County, NJ. During the chromate extraction process, varying amounts of lime and soda ash were added .

  Evaluation of Advanced Gravity and Magnetic Concentration ...

  Gravity concentration methods used for chromite beneficiation are based on differences between the specific gravities of chromite and gangue minerals. The fines (<100 µm) are however generally discarded as gangue from the gravity concentration processes. This results in a loss of fine chromite mineral to the tailings stream due to the inefficiency of gravity methods in the fine particle size ...
