difference between iron ore and iron sand

  • Iron ore - Wikipedia

    Iron ores consist of oxygen and iron atoms bonded together into molecules. To convert it to metallic iron, it must be smelted or sent through a direct reduction process to remove the oxygen. Oxygen-iron bonds are strong, and to remove the iron from the oxygen, a stronger elemental bond must be presented to attach to the oxygen. Carbon is used because the strength of a carbon-oxygen bond is greater than that of the iron-oxygen bond at high temperatures. Thus, the iron orIron and iron ore are closely related but possess distinct attributes that make them valuable in different ways. Iron, as a chemical element, exhibits exceptional strength, ductility, Iron vs. Iron Ore - What's the Difference? This vs. ThatIronstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore Ironstone - Wikipedia
