reduce magnetite to sponge iron in rotary hearth furnace

  • rotary kiln iron ore

    NOx Formation in Rotary Kilns for Iron Ore Pelletization. The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing.
