Iron Ore Pelletizing Process An Overview IntechOpen

Iron Ore Pelletizing Process An Overview IntechOpen

Jul 11, 2018 The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Abstract The disintegration behavior and mechanism of iron ore pellet in simulated shaft furnace conditions were investigated in details. Effects of temperature, reducing gas and gangue compositions were emphatically discussed. It was found that pellet disintegrated acutely as reduced by H2/CO = 0.8 at 550 C. Gangue minerals in pellet were proved to ease the disintegration in various degrees.
