How to Treat Wastewater from Iron and Steel Industry ...
When chemical treatment is used, the water is generally reused in the mill; it may be passed through cooling towers, especially in the warm weather months. The recovered scale is sintered for use in the Blast furnace or open hearth furnaces. Mill scale is comparable to high grade iron ore and is thus a salvaged material of considerable value.

Steel in Ancient Greece and Rome
Iron ore and a carbonaceous material were added together in a crucible, this was called the charge. The charge was placed at the top of the furnace and the blast applied to the bottom[19, 20]. If held at a sufficiently high temperature for a long time the bloom would absorb enough carbon to reduce the melting point of the iron.
