Iron ores are rocks and minerals from which metallic iron can be economically extracted. . The thermodynamic barriers to separating pure iron from these minerals are .. Magnetite is magnetic, and hence easily separated from the gangue . the ore to the point where the crystallized magnetite and quartz are fine enough.
