Effect of Iron Ore Concentrate on Sintering Properties

The portion of −20 µm in iron ore concentrate favoured the granulation and the productivity in conventional sintering, but the portion of +45 µm had the reverse effects. With increases in finer commercial concentrates (10–40 mass%) combined with low grade ore (10–20 mass%) in iron ore blends, the productivity also did not obviously change.
