Iron Ore In Sweden Magnetite Or Haematite
Why we use hematite over magnetite as iron ore?
Answer (1 of 5): The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasing the porosity and increased indi...

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 ...
