Abstract
PROCEDE D'ELIMINATION DE COMPOSES ORGANIQUES DU CYCLE DE PRODUCTION DE L'ALUMINE SUIVANT LE PROCEDE BAYER. IL CONSISTE A CHAUFFER LA LIQUEUR A RECYCLER OBTENUE APRES PRECIPITATION, A 120-350C, A Y DISPERSER DE L'OXYGENE ET A EN SEPARER LES PRODUITS DE DECOMPOSITION SOLIDES DES IMPURETES ORGANIQUES. ON PEUT AUSSI EFFECTUER LES OPERATIONS DE CHAUFFAGE ET DE DISPERSION D'OXYGENE SUR UNE PARTIE SEULEMENT DE LA LIQUEUR DEVANT ETRE INTRODUITE AU STADE DE LA DIGESTION, PUIS LA COMBINER DANS L'APPAREIL DE DIGESTION A LA BOUILLIE EN CIRCULATION A DIGERER, ET ELIMINER LES PRODUITS DE DECOMPOSITION SOLIDES DES IMPURETES ORGANIQUES DE LA LIQUEUR D'ALUMINATE AVEC LA BOUE ROUGE. LE DESSIN ILLUSTRE POUR DEUX VARIETES DE BAUXITE (COURBES 1 ET 2) LA REDUCTION DE LA TENEUR EN COMPOSES ORGANIQUES DE LA LIQUEUR TRAITEE EN FONCTION DE LA TEMPERATURE.
