Exmaples of extraction with carbon (as coke)

Iron, for example, is extracted from iron ore in the blast furnace. Iron ores, such as haematite contain iron oxide, which can be reduced using carbon to obtain the iron. This reaction looks like this: 2Fe₂O₃(s) + 3C(s) → 4Fe(l) + 3CO₂(g) , Iron oxide + Carbon → Iron + Carbon dioxide
