  • Novel insights into the reoxidation of direct reduced iron (DRI)

      Further, the deeper iron atoms are more exposed after the defected iron surfaces combine with O 2, greatly increasing contact opportunities of Fe O 2. Therefore, the reduction time should be appropriately extended to decrease the surface defects of new iron, and other wet ball mills should be selected for the treatment of DRI produced by
