Iron Ore Pelletization Techniques

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.
