  Novel Technology for Comprehensive Utilization …

  2023128 · Twenty different iron ore pellets, consisting primarily of Hematite (Fe2O3) phase, were subjected to ‘simulated’ reduction studies. A wide range of reduction time periods, Rt of 122 to 211 minutes, were obtained. Detailed microstructural characterizations were then conducted at different locations of ten selected specimens. The Rt did not …
