Extracting ores Mining of mineral resources Siyavula

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air oxygen in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:
