  • Roles of Alumina and Magnesia on the Formation of SFCA in ...

    The roles of A1 2 O 3 and MgO on the evolution of phases in iron ore sinters have been investigated by simulated sintering in the laboratory using natural ores, commercial grade limestone and analytical grade A1 2 O 3 and MgO. A1 2 O 3 may not be necessary for the formation of SFCA in sinters if the sintering temperature is below 1300°C and the sintering time is short.

  • The FINEX Process :: Total Materia Article

    Molten Iron is produced directly using iron ore fines and noncoking coal rather than processing through a sinter plant and coke ovens as traditional blast furnace route. In the Finex process, iron ore fines are charged into a series of fluidizedbed reactors. The fines pass in a downward direction where they are heated and reduced to directreduced iron (DRI) by means of a reduction gas ...

  • What are manganese ore fines and how are they sintered?

     · Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a lot of fines," Hockaday explained. "But they can't sell them, as furnaces won't buy materials that are too fine." So the mines separate out the fines, and agglomerate them together ...
