  • Chromite Ore - an overview | ScienceDirect Topics Chromite Ore - an overview | ScienceDirect Topics

    Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic

  • Chromite: The only mineral ore of chromium metal 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 Ore - an overview | ScienceDirect Topics Chromium Ore - an overview | ScienceDirect Topics

    The leading minerals of common chrome ores are chromium spinelides, which belong to the spinel group (natural spinel mineral MgAl 2 O 4 ). All of these minerals crystallize in space group Fd3m. The spinel group includes not only oxides, but also certain sulfides Cr 3 S 4, FeCr 2 S 4 (daubreelite), and others

    Chromite is isomorphous with the mineral Magnesiochromite and is easily confused with it, as they occur in the same environment s. Chemical Formula. FeCr2O4. Composition. Iron chromium oxide, often with some magnesium, sometimes with aluminum. Forms a series with the rarer mineral Magnesiochromite. Variable Formula

  • Mineral Resources - GCIS Mineral Resources - GCIS

    Ferrous minerals are produced from some 32 mines and 23 ferroalloys smelters. Over the last decade, increasing portions of the production of chrome, manganese and vanadium ore have been processed to value-added alloys in line with the drive for beneficiation, whereas the bulk of growth in iron ore production has been exported. Copper

  • Soldiers Delight - Maryland Soldiers Delight - Maryland

    All the ore mined in Maryland and the adjacent region in southeastern Pennsylvania was shipped to Baltimore, and nearly all of the chrome produced in the world between 1828 and 1850 came here. Isaac Tyson, Jr. established a chrome plant in Baltimore in 1845, and thereby gained a monopoly in the chemical use of chrome as well as in its mining

  • Chromite - an overview | ScienceDirect Topics Chromite - an overview | ScienceDirect Topics

    Chromite (Cr) occurs exclusively in mafic and ultramafic igneous rocks (Papp and Lipin, 2006).Although some Cr-based minerals such as crocoite (PbCrO 4), vauquelinite (Pb 2 Cu[CrO 4][PO 4]), uvarovite (Ca 3 Cr 2 [SiO 4] 3), and merumite (4(Cr,Al) 2 O 3 3H 2 O) are well known, chromite (FeCr 2 O 4) is the only one that is a commercially recoverable source of Cr (Sueker, 2006; Glastonbury et
