  • Limonite Wikipedia

    While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.

    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.
