摘要

As alkali additive, KCl catalyzes effectively the carbothermic reduction of pre-oxi- dized ilmenite, and the catalytic effect becomes more remarkable as the amount of KCl increas- es. During the carbothermic reduction, the gaseous product consists mainly of CO, and the partial pressure of which increases with reaction temperature. The EPMA and XPS of the par- tially reduced ilmenite ore and that of the used graphite as reductant showed that the potassi- um ions enter both ilmenite particles and graphite powders during reduction.
