Ilmenite - an overview | ScienceDirect Topics

It has been reported (Welham, 1996) that the solid-state prereduction of ilmenite by carbon takes place at >400 °C, followed by a carbon monoxide reduction to elemental iron at >1000 °C. After cooling and discharging from the reduction kiln, the product is dry-separated to remove the reduced iron and the excess char remaining after the reaction.
