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 % phosphorus [42]. The phosphorus in Western Australian goethite ores occurs in the form of solid solution.

Iron ore Wikipedia The Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
