    The process starts with up- draught drying (UDD), followed by down- draught drying (DDD), a preheating zone, a burn zone and a cooling zone. The zone for burning is called firing on traveling grates and in great kiln for kiln. In the burning zone, magnetite is transformed to hematite through oxidation.

  • Iron processing Britannica

    Direct reduction, in which iron ores are reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957. Few of these techniques survived, and those that did were extensively modified. Another alternative iron-making method, smelting reduction, had its forerunners

  • Pelletizing Wikipedia

    Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, and more. Pelletizing of iron ore. Processed Taconite pellets as used in the steelmaking industry, with a US Quarter shown to scale. Iron ore pellets are spheres of typically 6–16 mm (0.24

  • 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
