Most of the iron in the crust is combined with various other elements to form many iron minerals. An important class is the iron oxide minerals such as hematite (Fe2O3) magnetite (Fe3O4) and siderite (FeCO3) which are the major ores of iron.

What elements make up iron?

Iron is primarily obtained from the minerals hematite (Fe2O3) and magnetite (Fe3O4). The minerals taconite limonite (FeO(OH)·nH2O) and siderite (FeCO3) are other important sources. Huge amounts of iron are used to make steel an alloy of iron and carbon.
