Iron ore sintering is the process of heating iron ore fines, coke fines, and other materials to produce a semi-molten mass that solidifies into porous pieces of sinter with a size and strength suitable for a blast furnace. It is the second most energy-consuming process in steelmaking. Its main source of energy is the combustion of coke, which ...

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. …
