ABSTRACT:
In a process for producing ammonium metatungstate from ammonium paratungstate, ammonium paratungstate is introduced in the anode chamber of an electrolytic cell which is separated from the cathode chamber by an inert liquid permeable media, when a direct electric current is passed through the cell, ammonium ions migrate to the cathode compartment resulting in an increased concentration of metatungstate in the anode chamber.
