ideal ratio for iron ore

  • 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 or2020年5月26日  As these ratios change, the allowable proportions of lump, pellet and sinter iron ore will change, as will the required additions of limestone, production of slag, Overview of the Steel Production Process - Springer2019年10月30日  The present study has been undertaken to provide a detailed methodology for the chemical phase identification of different iron ores using XRD and Characterization and differentiation of iron ores using X-ray ...

  • Maximizing Iron Unit Yield from Ore to Liquid Steel

    The melting yield of DRI can vary depending on the iron ore chemistry, metallic iron content, carbon content, and melting practice. As we discussed in Part 1 of this series, the objective when selecting iron ores for direct As an important index of evaluating iron ore granules, the mass ratio of adhering layer to nuclei particles, R m, was measured for the studied iron ore granule types to help Experimental Study on the Physical Properties of Iron Ore Granules
