  • Process for the electrocatalytic reducing dissolving of refractory compounds of cerium
    Patent number: 5830342
    Abstract: The invention relates to an electrocatalytic or aero-electrocatalytic process for the reducing dissolving of a refractory compound of cerium such as CeO.sub.2. According to this process, the compound to be dissolved is introduced into an aqueous acid solution, e.g. a sulphuric solution, containing an electrochemical carrier constituted by one of the reducing or oxidizing species of a redox pair, whose redox potential is below +1.25 V/SHE, e.g. a ferric salt, a uranyl salt, molecular iodine or oxygen, and continuous generation and/or regeneration takes place by electrolysis of the reducing species of said redox pair.
