Characterisation of phosphorus and other impurities in

Nov 01, 2019· This method of phosphorus and impurity level reduction, however, has yet to implemented on a commercial scale and currently in Australia, the majority of iron ore feedstock production is a blend of low-P (<0.05 wt-% P) hematite-rich ores and high-P (>0.10 wt-% P) goethite-rich ores. 6. Summary

Characterisation of phosphorus and other impurities in

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

Iron ore Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.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.

Ladle Refining Furnace : Method for producing high quality

Along with sponge iron about 10-15% pig iron is added in induction furnace. Pig iron is produced using iron ore. A high carbon bath is required to take care of unreduced iron oxide present in the sponge iron. Once the melting is over, steel is taken to LRF station where it is refined in terms of sulphur and phosphorous.
