The most magnetic and common type is a lodestone. It consists of a brownish-black mineral called magnetite. Lodestones are natural compasses: Suspend one by a thread or wire and it will rotate until its magnetic field is aligned with Earthâs magnetic field. A magnetic field is the area around a material in which its magnetic forces can be detected.
The predominant minerals in DSO are usually the ferric iron oxides hematite (Fe 2 O 3), goethite (FeO(OH) and/or limonite (FeO(OH).nH 2 O). By comparison, magnetite ore typically has a much lower iron content when mined of between 25% and 40% Fe and in this form is unsuitable for steel making.The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe 3 O 4).y comparison, magnetite ore typically has a much lower iron content when mined of between 25% and 40% Fe and in this form is unsuitable for steel making.
