Iron Ore Pelletizing Process: An Overview | IntechOpen
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
Process of steelmaking
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.
