The conversion of iron oxides--Fe3O4 to Fe2O3

The conversion of iron oxides--Fe3O4 to Fe2O3. 2004. Q. I am a post-graduate student doing research in converting iron oxide Fe 3 O 4 (magnetite) into Fe 2 O 3 (hematite). As we know, Fe 3 O 4 can be considered as crystal 1:1 ratio of FeO (Fe +2) and Fe 2 O 3 (Fe +3) and FeO can be oxidized into hematite at 600 °C.
