Title (EN) SILICA REMOVAL PROCESS AND ALUMINA COMPOSITION USED THEREIN
(FR) PROCEDE D'EXTRACTION DE SILICE ET COMPOSITION D'ALUMINE UTILISEE DANS LE PROCEDE
Abstract: front page image
(EN)Silica is selectively removed from aqueous liquid containing a relatively large amount of borate (or boric acid) and a relatively small amount of silica using borate loaded alumina as the sorbant. The effluent can be passed through lithium loaded cation exchange resin to remove any dissolved aluminum.
(FR)La silice est extraite de maniere selective d'un liquide aqueux contenant une quantite relativement elevee de borate (ou d'acide borique) et une quantite relativement faible de silice en utilisant en tant que produit d'absorption de l'alumine chargee de borate. L'effluent peut etre fait passer au travers d'une resine a echange cationique chargee de lithium pour extraire l'aluminium dissous.
