Iron Ore Pelletizing Process: An Overview IntechOpen

Jul 10, 2017· 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. This chapter shows the status of the pelletizing process

Introduction to Iron ore Pellets and Pelletizing processes

Raw material preparation During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is

Iron Ore Pellets and Pelletization Process IspatGuru

Nov 26, 2014· Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.

Pelletizing Wikipedia

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines

FLOFORM ™ Iron Ore Pelletization

FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at 0.01-0.05% prior to balling, i.e. about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
