A Look at the Process of Pelletizing Iron Ore for
Iron ore must go through a lengthy preprocessing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate lowgrade 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
