  • Ancient iron production Wikipedia

    Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved away with the product. It also weathers well and hence it is readily available for study. The size, shape, chemical composition and microstructureof slag are determined by features of the iron-working p

  • How is Iron Extracted from Iron Ore Actforlibraries.org
