Abstract

Many types and large quantities of slags are generated from a wide variety of pyrometallurgical processes. Their safe and economical treatment is crucial for the sustainable development of society, with regard to environmental protection and resource preservation/recovery. This chapter provides an overview of 10 types of different slags: their sources, physicochemical characteristics, chemical and mineralogical properties, and their potential environmental concerns. The various routes for utilizing these slags in civil and environmental applications are reviewed with a particular focus on the leaching behavior of the potentially toxic elements. The efficacy of different treatments on the leaching performance of these slags and their use for stabilization/solidification of contaminated soils are discussed and research gaps are identified. Finally, future research directions are proposed, calling for more fundamental research and a holistic approach to utilize this material economically and safely.
