How is iron extracted using a blast furnace?
11-05-2020· Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. This is answered comprehensively here.Extraction Of Iron From Iron Ore The Blast Furnace,Feb 15 2021 The extraction of iron from its ores is quite a technical process.
