For economic utilization of low grade iron ore resource, a pilot scale study of iron ore direct reduction by rotary kiln (1.5 m 15 m) was carried out. In this work, the actual furnace burden and temperature distribution status in rotary kiln were in-situ measured. In addition, it is revealed that low-grade iron ore with a high pore properties, -FeOOH content, and gangue content can be upgraded to a high-grade iron ore with a low pore property (low specific surface area and pore volume), high Fe 2 O 3 content, and low gangue content using the above method. Therefore, this method is promising as a method ...
