classes of chrome mineral

  • Chromite: The only mineral ore of chromium metal

    A solid solution series exists between the mineral chromite (FeCr 2 O 4) and the isomorphous mineral magnesiochromite (MgCr 2 O 4). Intermediate specimens can be rich in iron ((Fe,Mg)Cr 2 O 4) or magnesium ((Mg,Fe)Cr 2 O 4). For convenience in communication, these minerals are often referred to collectively as "chromite."

  • Chromium Wikipedia

    Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard, and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing.

    So the mainly used chrome ore concentrating equipments are ore washbox (sometimes it is called jigger), concentrating table, spiral classifiers, etc. [Application]: The choice of chrome mineral processing technology is closely related with the physical and chemical properties of chrome ores. Because chrome ores are with weak magnetic, high magnetic separation matures gradually in chrome

  • Uses of Chromium Supply, Demand, Production, Resources

    Chromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. In nature, chromite deposits are generally of two major types: stratiform (layered) and podiform (pod shaped). Both types are associated with ultramafic igneous rocks.
