The iron ore pelletization is the process of converting iron fines less than 200 mesh (0.074 mm) into 8-16 mm pellets. Types of iron ore pellets Iron ore pellets are normally produced in two types of quality grades: DRI grade and BF grade. DRI pellets have a higher quality requirement, containing more than 67% iron content. They allow the …
