Processes for phosphorus removal from iron ore - a review - SciELO

Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden. A concentrate of sinter, moist, and without treatment was used. Chemical analysis showed the composition of 0.98% phosphorus (as P2O5 22.25%) and 60.85% iron. Nitric acid was chosen due to the low...

Iron ore - Wikipedia

Large cracks cause the iron or steel to break up. Smaller cracks can cause the object to fail during use. The degree of hot shortness is in direct proportion to the amount of sulfur present. Today iron with over 0.03% sulfur is avoided. Hot short iron can be worked, but it has to be worked at low temperatures.

In a similar way, sulphur enters the furnaces through coke and due to higher coke rate in our furnaces, it is difficult to maintain basicity at the desired level. RSP blast furnaces do not have high top pressure which can favour low silicon hot metal. The input used e.g. sinter and iron ore have little control on the percentage Al. 2.

Chapter 73. Iron and Steel

For iron making, the essential feature is the blast furnace, where iron ore is melted (reduced) to produce pig iron. The furnace is charged from the top with iron ore, coke and lizenithne; hot air, frequently enriched with oxygen, is blown in from the bottom; and the carbon monoxide produced from the coke transforms the iron...
