The invention relates to a method for obtaining or recovering hydrochloric acid from metal-containing solutions of hydrochloric acid by treatment by pyrohydrolysis and subsequent absorption or condensation of the gaseous hydrogen chloride formed in the process so as to form hydrochloric acid. According to the invention, a first sub-stream of the metal-containing solution of the hydrochloric acid is subjected to the treatment by pyrohydrolysis and a second sub-stream of the metal-containing solution is fed to the absorption column. The invention also relates to a device for carrying out the method according to the invention. |
