Characterisation of phosphorus and other

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

Characterisation of phosphorus and other

01.11.2019  To better understand the occurrence of phosphorus and associated impurities within goethite-rich iron ores, a detailed characterisation study was undertaken on a high-P Brockman iron ore from the Pilbara region of Western Australia. This paper is divided into a number of parts; (a) a brief review of phosphorus deportment within iron ores, (b) characterisation of high-P iron ores to

Different Types of Iron Ore - 911metallurgist

Impurities in Iron Ores. There are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making ...

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Iron ore - Wikipedia

Lower-grade 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. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

impurities of iron ore are removed by 」

To convert iron ore into metallic iron, oxygen and impurities must be removed.This process requires heat and a reducing agent, a substance that combines with the oxygen and releases it from the ore.. In the blast furnace process, iron ore, coke processed coal, and limestone the charge are poured into a vessel lined with refractory heatresistant brick.

Characterization studies on Agbaja iron ore: a

Iron ores with phosphorus content lower than 0.07% P are commercially desired as they are suitable for use in iron production. As a consequence, a lot of research efforts have been focused on phosphorus removal from high-phosphorus iron ore [20, 24, 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48] in a bid to reduce the P content to acceptable levels.
