A novel reductive alkali roasting of chromite ores for ...

The detailed chemical analysis of leachates after Cr 2 O 3 extraction shows that the acid leachates with residual concentrations of ∼150 ppm Cr 3+-ions can be recycled in situ for reusing water, for eliminating the risk of Cr 6+-ion formation from atmospheric oxidation. The novel extraction route may be able to displace the current oxidative process for chromite ore processing by retrofitting.
