Introduction to Iron ore Pellets and Pelletizing processes

Re-crystallization of iron oxides is essentially a physical process in which smaller particles consolidate into larger ones with the loss of surface energy. During the re-crystallization of iron oxides, continued growth of iron oxide crystals imparts sufficient strength. During the process, the grain growth for hematite starts at around 1100 deg C.

Effect of Blaine Fineness on the Quality of Hematite Iron

Iron ore pellets are largely characterized by inherent physical and chemical properties of ore as well as pelletizing conditions including induration time, induration temperature, etc. These parameters essentially vary with types of ores. The production of high-quality pellets from hematite ore is challenging because of high level of fineness (Blaine number) and induration temperature
