Magnetite Facts & Figures | The Magnetite Network

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.
