Reduction Of Iron Ore By Aluminium Equation

Apr 20 2015nbsp018332For the iron direct reduction a series of reactions occurred during the process of pellets reduction at T gt 843 K Fe 2 O 3 Fe 3 O 4 FeO Fe In the reduction series the transformations of Fe 2 O 3 Fe 3 O 4 and Fe 3 O 4 FeO are more rapid than that of FeO Fe thus the former two reactions can be ignored in the kinetics
