ELECTROCHEMICAL DISSOLVING OF METALLIC WASTES OF TUNGSTEN AND OF MOLIBDENUM IN AMMONIACAL ELECTROLYTES

There the new processing scheme of metallic tungsten wastes in thk ammoniacial electrolyte has been offered; the systematic studies for the exploration of anode dissolving of tungsten and of molibdenum in the solutions of ammonium hydroxide have been executed for the first time; the electric conductivity of given electrolytes has been explored; the temperature coefficient of specific electric conductivity has been determined. The optimum regime of anode dissolving of process of tungsten wastes and of molibdenum wastes has been determined; the design has been made; the semicommercial plant has been created at the Svetlovodsk Integrated Works of Refractory Metals and of Hard Alloys. The electrochemical processing method of metallic wastes of tungsten is at the stage of industrial tests. The application fields are the powder metallurgy, the non-ferrous metallurgy, the electric engineering enterprisesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
