| Abstract |
Behavior of the reduction of iron oxide in ilmenite and titanium slags by various solid carbons was investigated in the temperature range of 1000℃ l150℃. A laboratory scale rotary kiln for the prereduction was employed to study the effects of reduction time and temperature, using various carbons as reducing agents of the prereduction process. Maximum metallization (95%) of FeO in ilmenite was achieved at about 1100℃. The reduction process of ilmenite including newly confirmed phase (pseudorutile) could be expressed in four elementary reduction stages, and also the phase transformation of ilmenite and titanium slags during the reduction process was investigated with the aid of X-ray diffraction analysis and electronmicroscopy. |
