The potential iron loss in ore beneficiation of three hypothetical ores with a rich fraction consisting of haematite containing 1% Si and 67% Fe and having a fraction consisting of 70% SiO 2 and 10%, 15% and 20% Fe. In this calculation, the poor fraction is discarded and the iron loss is presented per ton of DR-pellet feed.

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO (OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements. Physical properties: Iron ore is usually hard, dense, and heavy.

For Australian iron ore grades, a major difficulty is that grades are estimated based on saleable production and not raw ore, despite the majority of iron ore requiring beneficiation before use (Mudd, 2009a, 2010b). Despite the issues with the data, the long-term trend is a gradual ore grade decline for saleable iron ore.
