  • A finite difference model of the iron ore sinter process

    Iron ore fines are agglomerated to produce sinter, which is an important feed material for blast furnaces worldwide. A model of the iron ore sintering process has been developed with the objective of being represen-tative of the sinter pot test, the standard laboratory process in which the behaviour of specific sinter feed mixtures is evaluated.

  • 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.
