Abstract
Magnesium is a promising material which has light weight, high specific strength, good ductility, good thermal conductivity and so on. China contributes more than 80% of the global magnesium production to the world each year. Most of Chinese magnesium metallurgy enterprises employ silicothermic reduction process-Pidgeon process, which produces huge amount of the reduction slag. The magnesium slag is not only the industrial waste polluting environment, but also the valuable raw materials which can be re-used. With rapid economic development in China resent years, there are increasingly urgent needs for comprehensive utilization of large amount of industrial solid waste. It has become the bottleneck that affecting sustained development of local economy. The team of authors in North Minzu University focus on the research of local industrial solid waste such as magnesium slag, electrolytic manganese residue and fly ash in recent years. The current book introduces the research results of the author team on recycling and utilization of magnesium slag. The main experimental data and cases come from the findings of the several national research projects such as National Program on Key Basic Research Project of China, International S&T Cooperation Project of China National 12th "Five-Year" Technology Support Programs undertaken by the authors. This book provides detail description of the research projects including technical roadmap, experimental data, and industrial test conditions and results and so on. It is expected that the book could provide a reference to scientists and engineers in relevant field and readers with interest.
