  • Manganese Ore Deposits

    Manganese ores can be carbonates, usually rhodochrosite but sometimes kutnahorite, or various silicates and oxides, the most common being braunite, bixbyite, and hausmannite [see table of common minerals]. The carbonates carry useful isotope signals for C and O [see stable isotopes of Mn deposits]. On a purely descriptive basis, Mn ores can be classed as sediment-hosted, volcanic-hosted, or

  • Manganese Ore an overview ScienceDirect Topics

    Manganese ores from different sources vary widely in their contents of manganese, iron, silica, alumina, lime, magnesia, and phosphorous. To produce standard ferromanganese (78% Mn) and a slag containing 30% MnO, the manganese-to-iron ratio in the charge must be 7.5:1. Since a single manganese ore of this ratio is seldom available, blending of ores from different sources is common practice to

    Excellent ores were found in the region of Magnesia, the region of northern Greece, just south of Macedonia, and this is how the trouble with manganese names started. Different ores from the region, which included both magnesium and manganese, were simply called magnesia. In the 1600s, the term magnesia alba or white magnesia was adopted for magnesium minerals, while magnesia nigra or

    The most common manganese mineral is pyrolusite (MnO2), usually mined in sedimentary deposits by open-cast techniques. Manganese occurs in most iron ores. Its content in coal ranges from 6 µg/g to 100 µg/g; it is also present in crude oil, but at substantially lower concentrations (1). Manganese is mainly used in metallurgical processes, as a deoxidizing and desulfurizing additive and as an
