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 ...

The iron and steel manufacturing sector directly accounts for 7–9% of global CO 2 emissions. Raw material preparation, such as iron ore sintering, pelletizing, and cock making, is the major CO 2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO 2 emissions without hindering eciency or increasing costs.
