FeO(OH)
Magnetite, hematite, goethite, in rock deposits.
Goethite Chemical formula: Fe3+O(OH) Crystal system: orthorombic bipyramidal Dana class: Hydroxides and oxides containing hydroxyl Synonym: limonite
Hematite.
Limonite is only a synonym for goethite. Goethite Chemical formula: Fe3+O(OH) Crystal system: orthorombic bipyramidal Dana class: Hydroxides and oxides containing hydroxyl Synonym: limonite

Hematite, Magnetite, Taconite, Goethite, Limonite and Siderite. Was that too many?
Hematite intermixed with Goethite is also known as Rainbow Hematite and is wonderfully iridescent.
Bauxite consists of goethite, hematite, gibbsite, boehmite, diaspore, kaolinite, and anatase.
Examples of iron minerals: magnetite, hematite, goethite, siderite, limonite etc.
The term "iron ore" is quite general, and can be applied to a number of different minerals, like hematite, magnetite, goethite, or pyrite.
Two of the most common ores are Haematite and Magnetite, the most common being Hematite.Some others are Taconite, Goethite, Limonite and Siderite.
