Lloyd M. Pidgeon in Canada pioneered the silicothermic reduction of calcined dolomite to metallic magnesium using the abundantly available dolomite mineral during World War II [9]. In the Pidgeon process, magnesium metal is produced from calcined dolomite under vacuum and at high temperatures using ferrosilicon as a reducing agent [10].
