Pidgeon Process - an overview ScienceDirect

Magnesium production in China is by the Pidgeon process and has been generally regarded as resulting in considerable atmospheric pollution. Initially the dolomite, from which the magnesium is to be extracted, is subjected to a calcining operation at about 1000 °C to remove carbon dioxide and the subsequent reduction process operates at about 1300 °C thus requiring a significant input of heat.
