Iron Ore Pellets and Pelletization Process – IspatGuru

26/11/2014  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. In the STG process, a stationary bed of pellets is ...
