  • Chromite: The only mineral ore of chromium metal

    What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering. Chromite

  • 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. The world's largest stratiform chromite deposits are found in South Africa, in what is known as the Bushveld complex. This is a

    Iron chromite is an inorganic mineral compound that is essential to several industries. It is often called chrome flour, chromite powder, or chromite flour. The chemical composition of is FeCr2O4. This compound is preferred for many industrial applications because of its high-heat stability, resistance to thermal shock, and resistance to corrosive gasses and slags. Chromite powder isn’t just

    Foundry sand use of chromite is a modern application. Sand is used to contain molten metal in a desired shape until the metal has solidified. Sand used in the foundry industry is washed, graded, and dried. Since silica sand is common and inexpensive, it is the most commonly used mineral. However, when physical or chemical conditions dictate, other sands are chosen, such as zircon, olivine, or

  • Origin of the UG2 chromitite layer, Bushveld Complex

    This forces supersaturation of the mixture in chromite, which upon crystallization accumulates on the magma chamber floor to form a nearly monomineralic layer. To evaluate this and other genetic hypotheses to explain the chromitite layers of the Bushveld Complex, we have conducted a detailed study of the silicate-rich layers immediately above and below the UG2 chromitite and another chromitite
