The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning
include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer
The iron ore pellet holds a pivotal role in the ironmaking process, enabling the utilization of high-grade ore and the upgrading of low-grade deposits [1].
