Steel and raw materials
98% of mined iron ore is used to make steel. Iron is one of the most abundant metallic elements. Its oxides, or ores, make up about 5% of the earth’s crust. Average iron content for high-grade ores is 60% to 65%, after taking into account other naturally-occurring impurities.6 • Iron ore is mined in about 50 countries. The majority of ironCalico or laminated sandstone. Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells.
