摘要： The invention relates to a method for producing metal hydroxides or alkaline metal carbonates by anode dissolution of the corresponding metals and precipitation of the hydroxides or alkaline carbonates in an aqueous medium. The anode dissolution of the metal components is carried out in the anode compartment of a three-compartment electrolytic cell. An aqueous auxiliary salt solution is fed to an intermediate compartment that is disposed between the anode compartment and the cathode compartment and that is separated therefrom by a porous membrane. An at least not alkaline metal salt solution is continuously taken from the anode compartment while an alkaline auxiliary salt solution is continuously taken from the cathode compartment. The at least not alkaline metal salt solution and the alkaline auxiliary salt solution are combined outside the electrolytic cell for the purpose of precipitating metal hydroxides or alkaline metal carbonates.

摘要： A process for reducing the content of alkali metal impurities (e.g., potassium) in ammonium metallate solutions is described. The process involves subjecting a feed solution containing ammonium metallate and alkali metal impurities to membrane filtration. The membrane filtration results in the formation of a retentate having a reduced level alkali metal relative to the feed solution, and a permeate containing substantially the balance of alkali metal. The permeate may also be further treated, to remove alkali metal there from, by passage through a cation exchange column, thereby forming a cation exchange treated permeate that may be combined with the retentate of the membrane filtration step.
