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.

Iron oreWikipedia

Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel—98 of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is "more integral to the global economy than any other commodity except perhaps oil ".

Beneficiation Plants and Pelletizing Plants for Utilizing

Grinding is a sub-process of finely grinding ore in advance such that the ground output can be physically separated into iron ore and impurities in the downstream sub-process. In many cases an autogenous mill (AG mill) or a semi-autogenous mill (SAG mill) is used for the primary grinding and a ball mill is used as the secondary for further
