The main component of magnetite is Fe₃O₄. Magnetite beneficiation methods are dominant in the separation of iron ore. The weak magnetic lean iron ore is often processed by gravity separation, magnetic separation, flotation, roasting, magnetic separation and combined processes; strong magnetic iron ore directly adopt magnetic separation.
