Iron Ore | ScienceDirect Iron ore is the primary raw material from which metallic iron is extracted to make steel. The rapid increase in crude steel production in the last decade has seen major expansions in world iron ore production from around 1 billion tonnes (Bt) in 2001 to over 2.9 Bt in 2012. PRODUCTION OF IRON AND STEEL POWDERS The Höganäs sponge iron process, is essentially a chemical process in which finely divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder.
