Abstract

Procédé pour extraire la zircone du zircon dissocié, suivant lequel on broie le zircon dissocié jusqu'à une granulométrie suffisamment fine pour dégager la zircone de la silice vitreuse avoisinante et on chauffe le produit broyé à une température de l'intervalle de 200 - 350 degrés C avec un excès d'acide sulfurique concentré pour convertir la zircone en sulfate de zirconium. L'excès d'acide sulfurique est d'au moins deux fois la quantité stoechiométrique.Process for extracting zirconia from the dissociated zircon, according to which the dissociated zircon is ground to a particle size sufficiently fine to disengage the zirconia from the neighboring vitreous silica and the ground product is heated to a temperature in the range of 200 - 350 degrees C with an excess of concentrated sulfuric acid to convert the zirconia to zirconium sulfate. The excess sulfuric acid is at least twice the stoichiometric amount.
