Abstract

L'invention a pour objet un procédé de préparation de magnésie à partir d'une matière première contenant du carbonate de magnésium, suivant lequel on met la matière première en suspension, on porte la suspension à 40-90 degrés C, on traite la suspension par l'anhydride sulfureux afin d'obtenir du bisulfite de magnésium soluble, on sépare les impuretés non dissoutes de la solution de bisulfite de magnésium, on précipite du sulfite de magnésium dans la solution, on sépare le précipité de la liqueur-mère et on recueille la magnésie à partir du précipité séparé.
