  • Identification and Description of Mineral Processing

    Chromium metal can be made either pyrometallurgically or electrolytically. In the pyrometallurgical method not shown, chromium oxide Cr 2 O 3 reacts with aluminum powder in a refractory lined vessel after being ignited with barium peroxide and magnesium powder. Chromium metal may also be made from the oxide by reduction with silicon in

  • Chromium processing | Britannica

    Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used. Ores high in alumina are preferred for processing
