  • Iron ore - Wikipedia

    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 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H2O), 55% Fe), or siderite (FeCO3, 48.2% Fe). 2015年1月1日  The mechanisms of reduction swelling of oxidized pellets were analyzed and investigated by SEM (scanning electron microscopy) and XRD (X-ray diffractometer) Mechanisms of swelling of iron ore oxidized pellets in high 2013年4月1日  Using visual studio net, matlab and open source computer vision library as development tools, combining with the ActiveX data objects database technology, the Temperature Field Simulation Model for Rotary Kiln of Iron Ore

    Typical harmful minerals in iron ore include pyrite, apatite, etc., which contain the harmful elements S and P. They are also weakly magnetic. However, if their magnetic Iron metal reacts with air, water vapor, nonmetals, and acid. Iron forms three different oxides: iron(II) oxide, iron(III) oxide, and iron(II, III) oxide. Iron(II) oxide can be formed Lesson Explainer: Properties and Reactions of Iron and Iron Oxides2016年7月1日  This study includes the characterisation and comparative study of the reduction of iron ore pellets and iron ore fines using saw dust char (SDC) as one of the Direct reduction of oxidized iron ore pellets using biomass syngas
