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

网页2020年9月18日  Bog iron is formed when ground-water picks up iron from iron-ore deposits, where that iron is then oxidized under acidic conditions to form chunks of iron minerals (goethite, magnetite, hematite, etc.), typically in smallish chunks. Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the

How Iron Was Made U.S. National Park Service

网页2022年2月16日  How Iron Was Made. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered

网页2019年7月17日  Based on modern experimental archaeology, it's possible to collect 10kg of bog iron in an hour. Carrying the ore can be a larger part of the labour involved than the actual harvesting of the bog iron." If we're talking just extraction, including short distances of walking, the 10kg of ore an hour is probably the figure to shoot for.
