Characterisation of phosphorus and other impurities in ...

Nov 01, 2019  1. Introduction. Australia’s iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).The phosphorus content of Australian iron ores is a

Characterisation of phosphorus and other impurities in ...

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
