  • How is iron extracted from a blast furnace? | AnswersDrive

    Iron is extracted from its ore, haematite, in a blast furnace. The molten iron is then tapped from the bottom of the furnace. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
