The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting. The configuration of iron ore powder in a blast furnace is more tightlypacked and restricts the air flow.

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 transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

1. Preprocessing Before pelletizing, iron ore has to go through a pretreatment stage. Generally, the lowgrade iron ore raw ore needs a beneficiation process to upgrade into iron fines that suit pelletization. The beneficiation process varies depending on the iron ore types and mineral properties.
