Iron ore pelletizing434 Кб. 2 Iron ore pelletizing Process flexibility There are two main processes for producing iron ore pellets: The Grate-Kiln system and the straight grate system.Pelletization process Pelletization is comprised of two main stages: (1) agglomeration and (2) induration. Pelletization is an agglomeration process of iron ore concentrates with a granulometry lower than 150 μm and low concentration of impurities [ 10, 11 ].

Pelletization is an agglomeration process of iron ore concentrates with a granulometry lower than 150 μm and low concentration of impurities [ 10, 11 ].

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ‘recipe’ for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests
Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and low-grade iron ore has been processed.

The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952.
