The particle size distribution of iron ore is a very important requirement to be characterized after its mineral processing. Materials containing a very fine particle size distribution are not adequate to be used directly in the reduction reactors, requiring to be agglomerated by different processes such as sintering or pelletizing. The main used reduction reactors are the blast furnace (BF ...
