Resource gathering is depending on leaner crude ores. Iron ore mining typifies this trend. To make lean taconite iron ores useful required a technologic breakthrough—pelletization. The shift to iron ore pellets has the advantage that they require less energy and labor per ton of molten iron than high-grade naturally concentrated ores.
During fluidized bed direct reduction, iron ore particles become sticky as metallic iron is formed on the surface, which may cause defluidization of the particles [11]. ... Thus, artificial granulation of iron ore particles may be an optimal solution for fluidized bed direct reduction. However, to the best of our knowledge, the relationships ...
