Abstract

PROCEDE POUR RECUPERER L'ALUMINE A PARTIR D'UN MELANGE SOLIDE CONTENANT ALCL ET NACL PAR ADDITION D'EAU EN QUANTITE SUFFISANTE POUR DISSOUDRE PRATIQUEMENT TOUT L'ALCL EN LAISSANT UNE CERTAINE PROPORTION DU NACL NON DISSOUS, BARBOTAGE D'HCL DANS LA SOLUTION AVEC PRECIPITATION D'ALCL, SEPARATION DU PRECIPITE ET, EVENTUELLEMENT, CALCINATION ET LAVAGE. LE BARBOTAGE D'HCL EST ARRETE LORSQU'ON A PRECIPITE UNE PROPORTION IMPORTANTE DE L'ALCL MAIS AVANT QUE LE RAPPORT NAOALO MONTE A 0,01 DANS LE PRECIPITE.
