REPORT ON ENVIRONMENTAL ISSUES OF CHROMITE MINING IN ...
Opencast chromite mining generate huge volumes of seepage water. Eventhough chromium in chromite is in the trivalent state, some hexavalent Cr(VI) is always formed due to certain complex reactions. If Cr(VI) containing mine drainage water is released untreated, can severely contaminate the nearby water bodies. Many mines have chrome ore beneficiation (COB) plants, where chromium .

Chromite: from the mineral to the commodity
An innovative study of geologic processes that can affect chromite ore beneficiation was applied to Vavdos chromite deposit (Greece) hosted in the Vavdos ultramafic massif belonging to the Halkidiki ophiolite of the Circum Rhodope orogenic belt. Here metamorphic modifiion of chromite led to redistribution of Cr 2 O 3 from chromite to silies. The effect of the redistribution is to lower ...
