Process for the preparation of metal hydroxides and/or metal oxides/hydroxides from corresponding metal ions and hydroxide ions, whereby the metal ions are formed in an electrochemical membrane process in which the metal ions are formed by anodic dissolution of corresponding metals in the anode compartment and the hydroxide ions by cathodic reduction of water in the cathode compartmentseparated by an anion-exchange membrane, and the hydroxide ions are transferred through the anion-exchange membrane into the anode compartment under the driving force of an electric field.
