The present invention relates to a continuous method for treating gases containing metal chlorides resulting from a ceramic process. The invention is characterized in that it includes the following successive steps: a) hydrolysis of the gas containing metal chlorides resulting from a ceramic process by placing said gas in contact with softened water having a pH ≥ 7, more particularly between 7 and 11, such that a hydrochloric acid solution is produced; b) treatment of the hydrochloric acid solution obtained in step a) by passing same over a weak anion-exchange resin such that the Cl- ions are exchanged for OH- ions and such that an aqueous solution having a pH > 7, more particularly between 7 and 11, is obtained; c) use of the treated solution obtained at step b) in step a). |
