Some of these effects include weathering and oxidation. The element chromium is most abundant in chromite in the form of trivalent (CrIII). When chromite ore is exposed to aboveground conditions, CrIII can be converted to CrVI, which is the hexavalent state of chromium. CrVI is produced from CrIII by means of dry milling or

Sep 19, 2018· Hexavalent chromium is extremely toxic, so trivalent chrome or trichrome tends to be more popular for modern applications. In 2007 hexachrome was banned for use on automobiles in Europe. Some chrome for industrial uses remains hexachrome because the corrosion resistance of hexachrome plating tends to exceed that of trichrome plating.
