Abstract. Thermochemical equilibrium calculations indicate the possibility of considerable fuel savings and CO{sub 2} emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite; (b) production of ferrosilicon from quartz sand, coal, and iron oxide; (c) silicothermic reduction of calcined dolomite by ferrosilicon to magnesium.

In the Pidgeon Process, magnesium metal is extracted from calcined dolomite under vacuum and at high temperatures using ferrosilicon as a reducing agent [1]. In this process, the finely crushed dolomite is feed into kilns where it is calcined. The calcined dolomite is then pulverized in a mill prior to mixing with finely ground ferrosilicon.
