Using the experience of British Steel's Teesside Works, the composition and treatment of steelmaking by-products, including slag and dust from the blast furnace, the desulphurising plant, BOS plant, secondary steelmaking plant, and millscale and sludge from rolling mill operations, are described. Many of the wastes can be readily recycled, while others require further processing. Techniques used for upgrading metal extracted from slag, for preparing BOS slag for use in agricultural fertiliser, the hydrocyclone pretreatment of blast furnace slurry, and the injection of oily millscale sludge or dust into the blast furnace, are explained. The amount of by-products going to landfill from Teesside Works has been substantially reduced since 1988, and the objective of zero landfill is expected to be achieved by the end of 1998.
