Kinetics of the Carbothermal Reduction of Ilmenite: Grain Pellet Model
Published in 2009
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 atmosphere. The proposed mechanism involves diffusion of CO gas through the ores of the pellet and through the product layer of iron in TiO2 matrix.
