  • 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 orcontents of iron carbonates and iron oxides. Production figures throughout this report do not (unless otherwise specified) refer to crude ore (ROM/Run of mine) or concentrate World Mining DataPrices for steel and diesel used in coal mining declined in 2020. The cost structure of coal mining is determined mostly by operating expenses such as mining cash costs (e.g. Prices and costs – Coal 2020 – Analysis - IEA
