In this study, direct reduction-magnetic separation process was applied to enrich phosphorus and iron to prepare Fe-P crude alloy from a high phosphorus oolitic hematite ore (HPOH). The results show that at lower temperatures and with absence of any of additives, Fe cannot be effectively recovered because of the oolitic structure is not destroyed. In contrast, …
Materials. Table I shows the chemical composition of the ultra-high-titanium vanadium–titanium magnetite concentrate (<75 μm) used in the experiment.
