Iron Ore - an overview ScienceDirect Topics

Mining iron ore or other iron-bearing materials from the ground is the first step to make iron and steel. 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 ).
