Beneficiation = Improve Concentration of Iron. Ore is either Hematite (Fe2O3) or Magnetite (Fe3O4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content.

Iron appeared in Africa by 600 BC, probably from Southwest Asia via Egypt, Nubia, and the Sahel corridor running south of the Sahara, and substantial iron working began in what is today Nigeria by the 300s. In most parts of the world, the use of iron largely displaced the prior use of bronze, and hence the "Iron Age" succeeded the "Bronze Age."
