For the purpose of efficiently and easily regenerating a sulfuric acid solution having a high concentration and a low impurity content from a metal sulfate-containing waste sulfuric acid solution and waste liquor formed during acid cleaning which are discharged from titanium (IV) oxide-production process carried out according to the sulfuric acid method. titanium present in the metal sulfate-containing waste sulfuric acid solution is removed through a solvent-extraction treatment and then the solution obtained after the solvent-extraction is subjected to a diffusive dialysis treatment.

L'invention concerne un procédé permettant de régénérer efficacement et facilement une solution d'acide sulfurique présentant une concentration élevée et une faible teneur en impuretés, à partir d'une solution d'acide sulfurique usé et de la liqueur usée contenant du sulfate de métal, qui sont produits au cours d'une opération de nettoyage à l'acide et dégagés par le processus de production d'oxyde de titane (IV) réalisé selon le procédé à l'acide sulfurique. Ledit procédé consiste à éliminer le titane présent dans la solution d'acide sulfurique usé à l'aide d'un traitement d'extraction par solvant, la solution ainsi obtenue étant ensuite soumise à un traitement de dialyse diffusive.
