  • 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). 2022年1月1日  In recent years, the global dependence on iron ore, a vital strategic resource, has faced unexpected disruptions caused by geopolitical events and Introduction: Overview of the global iron ore industryFollowing World War II, Americans feared their iron ore supplies were depleted.
