    Effect of particle size on reduction behavior in iron ore ...

    When the iron ore particle size decreased to 38 µm, almost the whole reduction of the iron ore achieved at 1200°C. The X-ray diffraction analysis of this mixture showed that metallic iron phase occupied an important position in the residue. This indicated that the iron ore particle size of 38 µm was sufficient to complete the reduction. 3.2.

    The ore is crushed and milled together with water in tumbling mills, so called ball mills, where the balls have been replaced by iron rods in an iron drum (about 2 m60.5 m), and rotated by an electrical motor (2.5–3 Hp per drum). After 6–10 h of milling, the particle size is smaller than 0.35 mm and about 60% smaller than 0.2mm(seeFig.2).
