Iron ore - Wikipedia

Phosphorus (P) has four major effects on iron: increased hardness and strength, lower solidus temperature, increased fluidity, and cold shortness. Depending on the use intended for the iron, these effects are either good or bad. Bog ore often has a high phosphorus content (Gordon 1996, p. 57).

Iron Ore - Mineral Fact Sheets - Australian Mines Atlas

The palaeochannel deposits composed of pisolitic limonite are the next in importance and are prized for their low impurities such as phosphorus. They are not as rich in iron as the BIF enrichment ores. Those mined usually contain 57%-59% Fe. Detrital iron ore deposits, including scree and canga deposits, are found.

Phosphorus distribution in BIF-derived iron ores of Hamersley .

Synopsis. The 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 criti- cal when techniques are being devised to upgrade.

Iron processing | Britannica

Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66 percent iron, there are many in the 50–60 percent range. An ore's quality is also influenced by its other constituents, which are collectively known as gangue. Silica (SiO2) and phosphorus-bearing.
