Abstract

L'invention concerne un perfectionnement au procédé de récupération du molybdène à partir de déchets qui font l'objet de la demande de brevet français n degrés 76 03674. Ce procédé perfectionné consiste à additionner les déchets sous forme divisée, de carbonate de soude en poudre, puis d'eau, puis à cuire le mélange et, enfin, à le traiter à température ambiante par du gaz carbonique. Les autres étapes du procédé ne sont pas modifiées. On évite ainsi la précipitation d'alumine et on obtient un hydrate de molybdène encore plus pur.
