How Is Iron Ore Reduced In The Blast Furnace
Mar 10, 2021 hii friend here is your answer, 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.
