Nigeria is blessed with all the raw materials required for steel development including iron ore, coal, natural gas and limestone. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe 2 O 3) or magnetite (Fe 3 O 4). About 98 percent of world iron ore production is
