In the Blast Furnaces, we melt iron ore into liquid iron at high temperatures. Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising ...

— Due to the reduction of the solidificatoin point by diffused carbon into the reduced iron, it begins to melt in the hotter zones of the blast furnace. Now the inner ore layers also come into contact with the carbon or the carbon monoxide gas and can be reduced to iron and then carburized. Gradually all the iron ore is reduced, carburized and ...

— Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
