Developments in iron ore comminution and classification ...

 · The iron ore in this area contains a large volume of fines (20–30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen. Vale initially considered wet-process screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.
