Abstract

La présente invention concerne un procédé de production de magnésium métallique selon un processus silicothermique à circulation sous vide et un appareil associé. Le procédé comprend les étapes suivantes consistant à : faire passer périodiquement du ferrosilicium en fusion (109) de 1350 à 1600 °C et de la poudre de minerai de magnésium contenant de la magnésie mélangée à travers un récipient sous vide (104) présentant un vide de 350 à 10000 Pa à la manière d'un flux en circulation, puis à collecter du magnésium liquide (201), autrement dit de la vapeur de magnésium libérée par condensation. L'appareil comprend un récipient de chauffage (101) et un récipient sous vide (104) raccordés à un tube plongeur ascendant (102) et à un tube plongeur descendant (103) dont les extrémités inférieures sont immergées dans le ferrosilicium en fusion (109) dans le récipient de chauffage (101). Un dispositif de soufflage de gaz inerte est inséré dans la paroi du tube plongeur ascendant (102). Le procédé et l'appareil associé permettent d'améliorer la productivité.
