  • Methods and systems for reducing chromium containing raw material
    Patent number: 9534275
    Abstract: A method for reducing a chromium containing material, comprising: combining the chromium containing material comprising chromium oxide with a carbonaceous reductant to form a chromium containing mixture; delivering the chromium containing mixture to a moving hearth furnace and reducing the chromium containing mixture to form a reduced chromium containing mixture; delivering the reduced chromium containing mixture to a smelting furnace; and separating the reduced chromium containing mixture into chromium metal and slag. The method also comprises agglomerating the chromium containing mixture in a granulator or the like. The chromium containing mixture has an average particle size of less than about 200 mesh (about 75 ?m).
