METHOD FOR RECOVERING METAL MAGNESIUM

PROBLEM TO BE SOLVED: To effectively recover metal magnesium from a transporting vessel of the metal magnesium containing impurities by accommodating the transporting vessel into a reaction vessel, connecting this reaction vessel with a condensing vessel, reducing the pressure in the reaction vessel and the condensing vessel and heating the reaction vessel in a specified temperature range. SOLUTION: A cover body 12 in a reaction vessel 10 is opened and a supporting member 40 is disposed in the reaction vessel 10. The connecting base part of a connecting part is disposed on the base part, and a receiving part is disposed at the upper part of the connecting part. The metal magnesium transporting vessel 50 is installed in the reaction vessel 10. The reaction vessel 10 and the condensing vessel are connected, and the heating of the reaction vessel 10 (750-1,000 deg.C) and the cooling of the condensing vessel are executed, and the reduction of the pressure in both vessels is started, and the reached degree of vacuum is made to be 0.05-0.1 Torr. When the degree of vacuum in each vessel is lowered to a prescribed degree of pressure reduction, the heating is stopped, the reaction vessel 10 and the condensing vessel are cut off an the reaction vessel 10 is cooled. After cooling near a room temperature, the metal magnesium in the condensing vessel is recovered.
