This study proposes a synergistic treatment method for BOF slag and copper via oxidation–magnetic separation, with the dual goals of preparing MgFe2O4 magnetic material stabilizing non-magnetic slag. The effects addition, oxidation temperature time on phase transformation morphology during process are investigated. results show that addition can release simple iron oxides FeO Fe2O3 from iron-containing phases slag, promoting synthesis MgFe2O4. Furthermore, have significant influence size particles. To obtain material, optimum parameters were used, an degree Fe2+ 95.85% yield 90.31%. In main was Ca2SiO4, both free CaO MgO eliminated, indicating potential application in construction materials. technology maximizes resource utilization valorization metallurgical solid waste.
