· Phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes, forming iron phosphides that make steel brittle. Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.07–0.08 wt-% P on the iron ore 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.
