Review of Cr(VI) environmental practices in the chromite

Nov 01, 2017Previously it was proven that dry milling of chromite ore (and other Cr containing materials) leads to Cr(VI) formation (Beukes and Guest, 2001, Glastonbury et al., 2010). Although not common, some chromite ores, e.g. chromite of the Sukinda belt of Orissa (India) might contain Cr(VI) that occurs naturally (Section 2 ) ( Godgul and Sahu, 1995
