Chromite - Wikipedia

Chromium extracted from chromite is used on a large scale in many industries, including metallurgy, electroplating, paints, tanning, and paper production. Environmental contamination with hexavalent chromium is a major health and environmental concern. Chromium is most stable in its trivalent (Cr(III)) form, seen in stable compounds such as natural ores. Cr(III) is an essential nutrient
