  • The Blast Furnace

    Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content. Pellets are produced from this lower iron content ore. This ore is crushed and ground into a powder so the waste material called gangue can be removed. The remaining ironrich powder is rolled into balls and fired in a furnace to produce strong, marblesized pellets that contain 60% to ...

  • Sulphur in Steels – IspatGuru

     · S in steel is introduced through iron ore and fuel (coal and coke). The removal of S during steel making is a tedious and difficult process. S is normally regarded as an impurity in steel and is required to be reduced to the limits of practicality. However steels which are to be machined need a certain minimum S content for proper chip formation. Where machining constitutes a major fraction of ...

  • Processes and Procedures in the Extraction of Iron ...

     · The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

    In this study, we propose a novel sulfurbased denitrifiion process by coupling with iron(II) carbonate ore (SICAD system). The ore was demonstrated to play roles as the buffer agent and additional electron donor. Moreover, the acid produced through sulfur driven denitrifiion was found to promote the Fe(II) leaching from the ore and likely extend the reaction zone from the surface to the ...

  • LiquidRedox Process Used for Sulfur Removal on an FPSO

     · Removal of sulfur from the unit is accomplished by directing a slipstream of circulating solution to a pressure belt ­filter. The filter uses highpressure air and wash water to recover solution and produces a filter cake consisting of 65 wt% sulfur and 35 wt% dilute solution (mostly water). Consequently, for every pound of sulfur removed from the gas stream, approximately lbm of .
