Abstract

This chapter mainly discusses the magnesium (Mg) slag generated in silicon thermic reduction of magnesium by Pidgeon process. Fluoride and fine dust in the slag and also the huge quantity of the slag (six to seven times of the magnesium produced) cause a big problem of environmental pollution, which can be eliminated by different technologies. First, it is discussed about the mechanism of the slag dust generation, the pellets disintegration, experimental results for slag volume stabilization, and dust controlled by adding several mineralizers. The second part of this chapter discusses the behavior of fluoride in Mg slag by Pidgeon process through a pilot trial facility, followed by the description of the utilization of F-free mineralizers in place of calcium fluoride (CaF2) in magnesium production for the elimination of fluoride contamination. The last part discusses the utilization of stabilized magnesium slag instead of lime as a fluxing medium for steel smelting and the use of the mixture of magnesium slag and manganese residue to make sulphoaluminate cement clinker.
