    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. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials from the iron content. This processing works to transform raw, mined iro
