WO2016120529A1 - Method for producing

The invention relates to a method for producing titanium oxide-containing slag and pig iron from ilmenite. The method is characterized in that it comprises the steps: a) pre-reducing ilmenite in the presence of reductant in a prereduction reactor to metallize at least part of iron in the ilmenite; b) optionally removing unreacted reductant and gangue from the pre-reduced ilmenite; and c
