Extraction of iron notes

Apr 17, 2020

It is called pig iron. Pig iron is melted with scrap iron and coke in the presence of hot air to form cast iron, which contains only 3% carbon. Cast iron is heated in a reverberatory furnace lined with haematite, which oxidises carbon to carbon monoxide to get wrought iron or malleable iron, the purest form of iron. Fe 2 O 3 + 3C → 2Fe + 3CO

    EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). 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
