CHROMIUM : Chromium is the brittle, lustrous and hard chemical element that belongs to the group of spinel. Chromite grains are commonly found in large mafic intrusions and are also found in metamorphic rocks on the earth's crust. Chromite, which is an iron chromium oxide (FeCr2O4) is the only ore present to produce the element chromium.
