Über dieses Buch

This open access book introduces the harmless handling/recycling of magnesium slag , the process of magnesium silicothermic reduction (Pidgeon process)which the slag was produced, and . the magnesium resources, layout of the industry of the world. Examples and experimental data in this book are from the author group’s research programs, as well as the rencent researches in China. The book could provide precious reference to scientists and engineers in the field of recycling and environment friendly use of the industrial solid wastes. It could also be used for researchers and students who are interested in relevant field.

Chapter 1. Overview of Magnesium Metallurgy
Abstract
Human beings discovered magnesium compounds as early as the seventeenth century. In later years, the magnesium alloy has been used in our daily life. In this section, we discuss the magnesium mineral resource, magnesium smelting technology, the history of magnesium industry and the comprehensive utilization of magnesium slag. We believe that it is worthwhile to investigate the magnesium and ralated technology which will make our life better.

Chapter 2. Magnesium Smelting via the Pidgeon Process
Abstract
At present, there are two main magnesium smelting methods: electrolytic method and reduction method. Compared with the electrolytic magnesium smelting process, the Pidgeon process has the advantages of simple and mature process flow, small investment, short construction period, multiple heat sources, good magnesium quality, low power consumption, and good utilization of coal, natural gas, heavy oil, gas and so on.

Chapter 3. Magnesium Slag Generated by Reduction Smelting Using Pidgeon Process
Abstract
The generation process and behavior of magnesium reduction slag via Pidgeon process are described in this chapter. Main compositions, phases, particle size distribution and harmful elements in magnesium slag were analyzed. The state and development of the techniques of treatment and effective use of magnesium slag were reviewed. The advantages and technical challenges of integrated utilization of magnesium slag were proposed.

Chapter 4. Decontamination of Magnesium Slag
Abstract
Magnesium slag is a valuable resource when proper disposal and utilization are adopted. The main pollution of magnesium slag caused are dust pollution and fluorine pollution. Formation mechanism of fine magnesium slag dust is investicated. Alike steel slag, phase transition of dicalcium silicate in magnesium slag around 500 °C brings volume expansion, which causes the disintegration and powdering of magnesium slag. Chamical stabilization experiments of the slag were carried out. The effects of phosphorus compounds, boron compounds and rare earth oxides doping on stabilization of magnesium slag was discussed. Catalytic action of calcium fluoride on magnesium smelting was revealed. Fluoride-free mineralizers for magnesium smelting were tested in industrial scale.

Chapter 5. Resource Utilization of Magnesium Slag
Abstract
The industrial solid waste recycling team at North Minzu University has done much research on resource utilization of magnesium slag. This chapter mainly introduces a discussion of resource utilization of magnesium slag. This includes the use of magnesium slag to prepare glass ceramics, porous ceramics, and sulfoaluminate cement clinker, fixing/stabilizing heavy metals in acidic residue generated by lead-zinc smelting, and modifying copper slag.
