• Chromite Wikipedia

    Chromite is a mineral that is an iron chromium oxide.It has a chemical formula of FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4). A substitution of the element aluminium can also occur, leading to hercynite (FeAl 2 O 4).

  • Chromium processing Britannica

    Pure chromium is produced either by the thermal reduction of Cr 2 O 3 with aluminum or by the electrolysis of trivalent chromium solutions. The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F).
