IRON AND STEEL

The iron and steel industry, including primary and secondary producer s, is composed of 79 companie s that produce raw steel at 116 locations. Iron is generally produced from iron ore (t aconite) in a primary mineral production process, while steel is produced using both primary and secondary processes. Primary production refers

Steel making process – ArcelorMittal

Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron content varies.
