  • From ore to steel – ArcelorMittal

    Finegrained iron ore is processed into coarsegrained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made. ArcelorMittal has a

    The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO3). Huge quantities of The third option for pig iron is to push the refining process even further and create steel, which we'll examine on the next page.

  • What is the method of production of pig iron by using a blast

    Pig iron is produced in blast furnace by reducing iron ore with carbon monoxide( indirect reduction ) and carbon ( direct reduction ). Raw materials in blast furnace are iron ore, metallurgical coke and suitable fluxes like dolomite, lime etc. Metallurgical coke is converted into desired carbon monoxide with the
