    Iron Ore fines that may contain Direct Reduced Iron (C ...

    The iron in a cargo of iron ore is chemically bound with other elements and therefore it contains no metallic (or free)iron. If the cargo contains any metallic iron (Feo), then it must be a DRI derivative: DRI (A) and (B) cargoes typically contain about 85% metallic iron,whereas in blends containing DRI (C) it can be as low as1% or 2%.

    Iron ore

    Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

    Titration is a conventional technique for determining the FeO content, but it is an operator prone and time intensive procedure. Conclusion. The QPA results for the FeO content are in good agreement with the expected values for both samples. This corroborates the ability of the XRD to rapidly determine the valence state of iron ore within few ...

    DETERMINATION OF FEO IN CHROMITE ORE – MSK

    The chromite ore is normally having a composition of FeCr2O4 which may be written as In some ore Fe is partially replaced by Mg as (Fe, Mg) Cr2O4. The ore may have Fe in other form besides being present in the spinel. An accurate determination of FeO content is extremely important in chromite ores and refractories made with them.
