magnetite iron ore grinding mills For magnetite features high hardness and very fine grained disseminated grain size, adopting the ordinary one-section grinding process is hardly to achieve the due production and monomer dissociation degree So the magnetite grinding technology adopts the two-section grinding process
Types of Iron Ore: Hematite vs Magnetite | Investing News ,
The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4) Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers
