Steel And Iron Slag

Steel and iron slag Oxide dusts, sludges, scales, slags and spent refractories are co-products of the iron and steel manufacturing process. These residues generally represent 6-7% of the whole steel production. Their production arises from the conversion of ores to iron, hot iron to steel, and from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. These by-products, especially in the past, were classified as waste and often stocked and or disposed in landfills, although they could be a valuable secondary raw material when recycled and properly reused. If treated correctly, they can be utilized both in metallurgical processes and in other industrial applications.
