  • Iron Chromite Applications and General Uses African

    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 FeCr 2 O 4. This compound is preferred for many industrial applications because

  • Iron(II) chromite Wikipedia

    Iron(II) chromite is an inorganic mineral composed primarily of chromium(III) oxide and iron(II) oxide compounds with the simplistic chemical formula FeCr2O4.

    Chemical Properties. Typical Chemistry: Cr2O3= 46-47%, FeO= 24.50%, Al2O3= 15.0%, MgO= 9.50%, and SiO2= 0.7- 1.0%.

  • Improving the Quality of Ferruginous Chromite

    The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.

  • Chromite --- Chrome Ore --- Chromitesand --- Chromite

    Chromite is the commercial name for iron chromium oxide (FeCr2O4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. Chromite occurs exclusively in ultramafic rocks such as dunite, peridotite, pyroxenite and serpentinite. High purity deposits are rare owing to

  • Iron(II) chromite Wikipedia

    Chromite, a FeCr. 2O. 4 contaning mineral. It is used as a commercial source of chromium and its compounds. It is also used as a catalyst in the synthesis of hydrogen (H 2) from the reaction between carbon monoxide and water vapor.

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

  • DIRECT CHROMIUM ALLOYING BY CHROMITE ORE WITH THE

    iron chromite with the presence of metallic iron was investigated by thermogravimetric analyse (TGA); up-scaling experiments (from 100 g to 500 g scale) by using the mixture of iron (both the pure iron powder and industrial iron scrap were tested), industrial carbon, and chromite ore were carried out in an induction furnace to investigate the reduction

  • Chromite an overview ScienceDirect Topics

    Chromite ore can be separated in a high-strength field, despite the presence of iron impurities. The choice of method depends on several factors, primarily the type of the gangue. In some cases, separation and dressing methods are optimized to take into account other useful elements, such as PGM (platinum group metals) in South Africa, where noble metals extraction (besides chromium) is of high importance.

  • Chromite: The only mineral ore of chromium metal
