4 Extraction of Iron in a Blast Furnace - King's General Science
This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3. Haematite is added to the top of the furnace along with coke (i.e. carbon) and limestone. Three reactions take place during this extraction. Firstly, the carbon in the blast furnace burns with the hot air to form carbon ...
