发明名称 Menetelmä titaanioksidia sisältävän kuonan ja raakaraudan tuottamiseksi ilmeniitistä, sekä laitos
摘要 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) smelting the pre-reduced ilmenite in an electric arc furnace to separate titanium oxide into a molten slag phase and pig iron into a molten metal phase. The invention also relates to a plant for titanium oxide-containing slag and pig iron production from ilmenite and to titanium oxide-containing slag and pig iron.
