Flotation Phosphorus High Iron Ore Agent

Characterisation of phosphorus and other impurities in goethite-rich iron ores – Possible P incorporation mechanisms …

 · 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.
