Iron Ore Beneficiation University of Newcastle

There is a large economic competitive advantage in beneficiating iron ore in the dry state, as this avoids the costs of removing the moisture that is added during wet processing. However, dry beneficiation presents more technical challenges than wet systems, due to the greater difficulty in maintaining dynamic stability and the complexity of a dry solids handling system.
