Abstract
Procédé pour la récupération de la magnésie de matières de revêtement La matière est traitée à la vapeur entre 100 et 300 degrés C pendant 1 à 50 heures et est ensuite soumise à une lixiviation par l'eau à une température de l'ordre de 60 degrés C au moins sous une pression de CO2 . On sépare ensuite les résidus solides et fait précipiter finalement les hydrocarbonates de magnésium dissous. Application aux briques réfractaires et autres déchets de réfection de fours.
