Review of Organic Binders for Iron Ore Agglomeration

22/05/2013 · Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from low-grade ores, concentrated, and agglomerated into round balls that are thermally hardened to form "pellets". Pellets are then transported to Blast Furnace or Direct Reduction operations where they

Iron Ore Pellets and Pelletization Process IspatGuru

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. In the STG process, a stationary bed of pellets is
