Molten oxidation process was considered to be a more suitable approach for recovering of iron value with crushing magnetic separation followed. Iron oxides could be precipitated from the molten iron silicate during oxidation while magnetite was preferred because of its intensive ferromagnetism and large crystal size. In the present study, oxygen partial pressure was considered to affect to the growth of iron oxides and it was implemented to find the favorable condition for the growth of magnetite and restrain of hematite.
