  • extracting iron from mill scale

    Extracting Iron Ore From The Ground The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine grained iron ore is processed into coarse grained clumps for use in the blast furnace.

  • How is iron extracted from a blast furnace? AnswersDrive

    Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
