Notes On Extraction Of Crude Metal

The metal loses the oxygen, so it is reduced. The carbon gains oxygen, so it is oxidised. Reduction of iron is shown in the following chemical equation: iron oxide + carbon → iron + carbon dioxide . Heating coal in the absence of oxygen forms coke. This is used as a source of carbon for metal extraction.
