Characterisation of phosphorus and other impurities

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.

2021-5-3  The quantity of phosphorus present in pig iron varies from 0.1 to 2.0%. It combines with iron to form Fe 3 P which embrittles cast iron. Phosphorus is introduced into iron from phosphate in the ore. Phosphates get reduced in the reducing atmosphere in the blast furnace and phosphorus is formed. This phosphorus combines with iron to form Ee 3 P.

Understanding the high-grade iron ore market

2021-3-26  Iron ore concentrates are ores that have been mechanically processed to increase their iron content and decrease impurity levels. Iron is not a rare commodity – it’s the fourth most abundant element in the earth’s crust, making up around 5% – but zones that can produce high-quality DSO are finite. Thankfully, there are ample resources ...
