Magnetit – Wikipedia
Magnetit, är en gråsvart järnoxid med formeln Fe 3 O 4.Magnetit kallas ibland svartmalm.. Magnetit tillhör det kubiska kristallsystemet och är till strukturen en spinell [3] där två av järnatomerna har laddningen 3+ och en har laddningen 2+. Formeln skrivs därför ibland Fe 2+ Fe 3+ 2 O 4.Magnetit bildas huvudsakligen under högt tryck och hög temperatur och …

Iron Production
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...
