iron ore processing for the blast furnace

  • Iron Ore Processing APM

    General process information. Highgrade iron ore is crushed for sizing, producing both fine ore as well as lump ore. To beneficiate lowgrade ore, lump ore is first grinded into finer particles called grinded ore. Both fine and grinded ores are then subjected to pretreatments before they can be charged into the blast furnace
