They usually contain considerable quantities of valuable metals and materials. Transforming these solid wastes from one form to another to be reused either by the same production unit or by different industrial installation is very much essential not only for conserving metals and mineral resources but also for protecting the environment. The sustainable development concept requires a more efficient management of waste materials and preservation of environment. The paper presents the basic characteristics of slag, analyses and it＇s modification by incorporating some essential plant nutrients and the possibility of its application as fertilizer was studied.展开更多
