Chromite
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 nutrientChromium ores are often classified based on their elemental composition and industrial use into: highchromium (46–55% Cr 2 O 3, Cr:Fe > 21) used for metallurgical processes, Chromium Ore an overview ScienceDirect Topics
Chromium
Chromium is a chemical element; it has symbol Cr and atomic number 24 It is the first element in group 6 It is a steelygrey, lustrous, hard, and brittle transition metal Chromium metal is valued for its high corrosion resistance and hardness A major development in steel production was the discovery that steel could be made hCommonly known as chrome, it is one of the most important and indispensable industrial metals because of its hardness and resistance to corrosion But it is used for more than the production of stainless steel Uses of Chromium Supply, Demand, Production, Resources
