The iron itself is usually found in the form of magnetite(Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Source:Wiki
iron and oxygen
Magnetite is an ore of iron, and therefore has economic value.
Iron is an element. Nothing is used in it.
The chemical formula of magnetite is Fe3O4.Iron: 74,41 %Oxygen: 27,59 %
Usually cast iron
It could be in any object made of iron. Magnetite was once the largest ore of iron.
The chemical formula of magnetite is Fe3O4 (contain iron and oxygen).
The formula for magnetite is Fe3O4. Magnetite is a mineral found in nature in the form of iron oxides. This ore is a natural magnet.
Skillets are normally made of the element 'Iron' (Fe).

Tri-Iron Tetroxide or also Iron(II,III) oxide. It is found in the mineral form of Magnetite
The iron oxide with the formula F3O4, called iron (II,III) oxide, is known as magnetite. There are also iron (II) oxide, FeO, and iron (III) oxide, Fe2O3, but they are not magnetite.
