A Look at the Process of Pelletizing Iron Ore for Steel

Preparing Iron Ore For PelletizingThe Pelletizing ProcessThe Process Development Behind Iron Ore PelletizingConclusionIron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
