Iron Ores
Its importance in older times is unclear to me because it was not distinguished from siderite or bog ore. Goethite forms by "weathering" of more primary iron ores like magnetite or pyrite, involving a change from Fe(II) compounds to the more stable Fe(III) form. It thus is often found in the "gossan" (Eisenhut = iron hat) of iron ore deposits.
