  • Inuence Of Oxide And Silicate Melt Phases On The Rdi Of

    The temperature in iron ore pelletizing process is as high as 13001320176C, so that a signicant amount of liquid slag forms in the pellets. The main components of the slag phases are SiO 2, FeO, Al 2O 3, CaO and MgO in various proportions. The slag or melt phase wets the solid surface and facilitates the diffusion and grain growth.

  • Iron Ore Agglomeration Technologies Intechopen

    May 18, 2017018332Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration.
