Abstract

La presente invencion proporciona un metodo para fabricar eficientemente una escoria conteniendo oxido de titanio a partir de un material incluyendo oxido de titanio y oxido de hierro, donde se suprime la reduccion de dioxido de titanio y se minimiza el consumo de energia electrica. El metodo incluye los pasos de: calentar una mezcla de materias primas incluyendo oxido de titanio, oxido de hierro, y un reductor carbonoso, o la mezcla de materias primas incluyendo ademas el oxido de calcio, en un horno reductor; reducir el oxido de hierro en la mezcla para forma hierro reducido; alimentar la mezcla resultante a un horno de fusion por calentamiento; calentar la mezcla resultante en el horno de fusion por calentamiento para fundir el hierro reducido y separar el hierro reducido de una escoria conteniendo oxido de titanio; y descargar del horno y recuperar la escoria conteniendo oxido de titanio.
