The kinetics of the ilmenite chlorination was studied between 600 and 950°C. The chlorination reaction rate was determined by monitoring the mass changes with a high-resolution thermogravimetric system. Non-isothermal and isothermal runs were performed. The mass loss was continuously monitored as a function of the reaction temperature, chlorine flow and sample mass. The solid residue and condensed phases were also analyzed by SEM, EDS and XRD
