• Reduction of Iron Ore Pellets, Sinter, and Lump Ore under ...

     · A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and ironbearing materials separately, which leads to a layered structure. The ironbearing materials consist of iron ore pellets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2. In the ideal situation, ironbearing materials ...

  • The MIDREX Process

    In the early days of direct reduction, there was a clearly discernible difference between iron oxide pellets intended for blast furnace use (BFgrade pellets) and those used to make DRI to feed an EAF. A "DRgrade" pellet typically has higher iron content and less silica, alumina and other gangue constituents than "BFgrade" pellets.

  • Iron Ore Pelletizing Plant

    Ironmaking blast furnace requires high air permeability during operating so the iron ore fines should be processed into iron ore pellets in the iron ore pelletizing plant in advance. During the processing of highgrade iron ores which don't need beneficiation, many ore fines are generated which are usually regarded as waste.
