	<span lang="EN-US">Reduction
kinetics of titanomagnetite concentrate briquettes produced from Rossetta-llmenite
ore via 1.5 liter/min hydrogen flow rate were investigated at different
temperatures ranging from 600¡æ to 950¡æ. It was found that the best reduction
properties were found at 950¡æ, so the kinetic models shown by the briquettes
at this temperature maybe: Diffusion control</span><span lang="EN-GB"> or </span><span lang="EN-US">Diffusion through ash layer
(crank-cinslling-Broushten equation). And the apparent activation energy
calculated for these models was 33.223 and 30.389 kJ/mole respectively. Also
the main crystalline phases of reduced briquettes at 950¡æ were metallic iron
(syn. Fe), rutile (syn. TiO<sub>2</sub>) and some traces of magnetite (Fe<sub>3</sub>O<sub>4</sub>).<o:p></o:p></span>
