Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are
Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that
Mining iron ore is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. [24] To convert it to metallic iron, it must be smelted or sent through a direct reduction process to remove the oxygen.
