Abstract

Procédé de préparation d'hydroxyde d'aluminium granuleux. Cest un perfectionnement du procédé Bayer où l'on ajoute du germe d'hydroxyde d'aluminium à une solution concentrée d'aluminate de sodium pour précipiter l'hydroxyde d'aluminium de ladite solution. Le perfectionnement consiste à ajouter de l'oxalate de sodium préparé par n'importe quel procédé connu à ladite solution. Application à l'industrie de l'aluminium
