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.
Steel - Wikipedia
Origins and production. Iron is commonly found in the Earth& 39;s crust in the form of an ore usually an iron oxide such as magnetite or hematite.Iron is extracted from iron ore by removing the oxygen through its combination with a preferred chemical partner such as carbon which is then lost to the atmosphere as carbon dioxide.
