Chromium is extracted from chromite ore. Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4). Companies in South Africa supply chrome ore from the lower and middle group chromitites of the Bushweld complex and from the upper group chromitite seam (UG2) in addition to platinum group minerals.
Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important applications. Other applications are in alloy steel, plating of metals, pigments, leather processing, catalysts, surface ...
