Iron ore - Wikipedia
Iron ores[1] 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
Energy Use in US Steel Manufacturing - Stanford University
Steel is simply low-carbon iron. As such, the steel manufacturing process begins by smelting iron ore (Fe 2 O 3 or Fe 3 O 4) in a blast furnace.This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of
