Management of Solid Wastes in the Iron and Steel Industry

The manufacturing operations in the plant under consideration are agglomeration of iron ore and sintering, pig iron manufacture, steel making, rolling mill operations, and pickling. Liquid slag, produced in the blast furnace, is granulated in water and used as a concrete additive. Other wastes are directed separately to sedimentation tanks.
