Ilmenite an overview ScienceDirect Topics

The Becher process involves several steps beginning with a reduction, in rotary kiln, of the iron oxides contained in the ilmenite feedstock largely to metallic iron using coal as the reductant as is done in the DRI process (Figure 10.8). This results in a mixture of metallic iron and titanium phases known as “reduced ilmenite.”
