Different Types of Iron Ore Mineral Processing MetallurgyIMPURITIES IN IRON ORESIRON ORE FORMATIONORIGIN OF IRON ORE BODIESMAGNETITELIMONITESIDERITEThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so called Bessemer

Iron Ore Sedimentary Rock Pictures, Definition More
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides hematite (Fe2O3) and magnetite (Fe3O4).
Geology, Prospecting and Exploration for Iron Ore Deposits
Apr 09, 2015Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earths crust.
