✦ Synopsis

This book introduces super gravity metallurgy in separation of valuable component in metallurgical slag. It collects the principle, apparatus and research for super gravity high-temperature metallurgy and the novel technology for selective crystallization and separation of various valuable components in different metallurgical slags by super gravity. Furthermore, the research results previously scattered in many journals and conferences worldwide are methodically edited and presented in a unified form. The book is likely to be of interest to university teachers, researchers, R&D engineers and graduate students in pyrometallurgy and extractive metallurgy who wish to explore innovative methods and technologies that lead to more efficient and environmentally sustainable utilization of metallurgical slag.
