  • Recovery Of Iron From High Phosphorus Oolitic Iron Ore

    Recovery Of Iron From High Phosphorus Oolitic Iron Ore

    The world's resources are dominated by low grade ore, though current world production of iron ore is largely by supply from deposits of high grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.Alkali leaching and acid leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12 for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions. The results show that phosphorus occurring as apatite phase could be removed by alkali leaching, but those occurring in the iron.

    The Australian iron ore industry has experienced decades of strong growth and is likely to remain a major producer of high grade ores to the overseas market with 15 or 24 Billion tonnes (Gt) of economic demonstrated resources (EDR) in 2008 (GA, 2009). The development of Australia’s iron ore industry followed the lifting of an embargo on iron.Phosphorus Iron. The combination of high purity iron and 0.45 Phosphorus creates a powder that is highly compressible and allows extremely high density (up to 99 of theoretical density) to be achieved during the SGT sintering process. This creates a mechanically tough finished component with excellent magnetic properties (very high saturation).
