Chromium metal was isolated in 1979 by Frenchman, Louis Nicolas Vauquelin. Since that time small amounts for free chromium have been found in rare minerals. Commercial chromium is obtained from chromite ore which is actually iron chromium oxide. Its name is derived from the Greek word for colour because of its compounds having intense colours.
Chromium ores were mined continuously from 1880 to 1962; production totalled 3,285,000 tonnes, with an average chromium metal content of 53 per cent (fig.10). During this period chromium ore mining produced more metal than nickel ore mining.
