By exposing chromite ore to aboveground conditions that promote weathering and oxidation, Cr-III may be converted to mobile Cr-VI. Dry milling (grinding) of chromite ore is now known to convert Cr-III to Cr-VI and efforts are required to avoid producing and spreading hexavalent chromium during mining activity.
