  • Specifications of iron ores required by steel plants for ironmaking ...

    Eighty per cent of the world's steelmaking is through the blast furnace route and hence the role of iron ore as a raw material and its quality become very critical to achieve steel with 2008年8月8日  Goethite is reported to occur as a ubiquitous phase in many iron ore types and is particularly abundant in the Precambrian banded iron ore formation of north Goethite Morphology and Composition in Banded Iron Formation, steel industry (blast furnace and direct reduction) (Wolff, 2009). Iron ore with a Fe grade less than 64.0%, such as the actual ores of Minas Gerais and Mato Grosso do Sul, must International Journal of Mineral Processing - UFOP

  • Mineral and Technological Features of Magnetite–Hematite Ores

    2021年3月24日  Iron is mainly present in the trivalent form—Fe 2 O 3 content ranges from 50.69 to 51.88%; bivalent iron is present in small quantities—the FeO content in the Figure 1 illustrates an example for a full-pattern Rietveld quantification of a lateritic iron ore sample.
