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 ...

1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.
