Froth Flotation of Iron Ores

In hematite and goethite ores, phosphorous tends to be dispersed and incorporated into the lattice of iron minerals. For example, more than 80% of Western Australian iron ore contains an average of 0.15% phosphorus [42]. The phosphorus in Western Australian goethite ores occurs in the form of solid solution.
