Potential Toxic Effects of Chromium, Chromite Mining and ...

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. Studies suggest that milling ores while wet or in a non-oxygenated atmosphere (i.e. nitrogen) will decrease Cr-VI formation. Preliminary observations have shown that the duration of milling also affects the amount ...
