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 …

Most reserves of such ore have now been depleted. 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. [1] Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". [2]

Phosphorus is a problem in ironmaking feedstocks, as phosphorus in iron gives the metal undesirable properties. Some iron ore sources have significant levels of phosphate minerals that are difficult to remove, and so use of ore from these sources requires the iron and steel plants to remove the excess phosphorus from the molten metal.

2.1. Iron Ore Sample Analysis. The high phosphorus oolitic iron ore used in this research was obtained from western Hubei in China. Table 1 shows the chemical composition of the ore examined by chemical analysis, indicating that iron content reached 51%, and phosphorus content was 0.52%. If phosphorus could be removed appropriately, the ores of this kind would be of great value in use.

AbstractThe Brockman Iron Formation is one of the most important sources of iron ore in Australia. The usable reserves are limited, however, by high phosphorus levels within some of the orebodies. Understanding of the nature and distribution of this phosphorus is critical when techniques are being devised to upgrade the ores for ironmaking.
