Iron ore Wikipedia. In the case of iron ore smelting the offgas from the furnace, consisting mainly of carbon monoxide and hydrogen, can be used for pre reduction of the other appliions of the process, such as reclaiming of alloying metals from baghouse dust, the produced gas is utilised as a fuel the raw material contains metals with high vapour pressures, for example zinc ...

13/03/2010 · The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the .

The ironores that are charged into the process go through fluidized bed reactors where they are heated and reduced to Direct Reduced Iron (DRI). The DRI is then charged into the melter gasifier where the final reduction and melting as well as the production of reducing gas by gasifiion of coal with oxygen takes place ( Schenk, 2011 ).
