Chromite Ore Procedure

Role of Chromite Mineralisation in Orissa

Classifiion of Chromite Ore: Chromite deposits have been classified broadly into two groups as stratiform and Alpine type. Stratiform deposits are sheetlike or lopolith in form, extend over large area and characterized by both rhythmic and cryptic layering, thickness of individual layers varying from a few centimeters to meters. This accounts for about 90% of the total chromite resources ...

Conversion of Chromium Ore Processing Residue to Chrome Steel

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 and roasted with pulverized chromite ore to a temperature between 1100ºC and 1150ºC under an oxidizing environment. Trivalent chromium in chromite ore was oxidized to hexavalent chromium. The ...
