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.

Disposal of the salt slag produced during the processing of aluminum dross and scrap is of particular interest to the secondary aluminum industry.

The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is converted to a cement-like material by rapidly cooling it with water. This rapid cooling, called ...
