Collections: Iron, How Did They Make It? Part I, Mining

There are quite a lot of ores of iron, but not all of them could be usefully processed with ancient or medieval technology. The most commonly used iron ore was hematite (Fe 2 O 3), with goethite (HFeO 2) and limonite (FeO(OH)·nH 2 O) close behind. Rarer, but still used was magnetite (Fe 3 O 4) and siderite (FeCO 3).
