FIELD: methods of manufacture of cell diaphragm components for electrolytic extraction of metals from aqueous solutions.
SUBSTANCE: diaphragm component formed from diaphragm cloth has at least one side surface with vertical edges and horizontal edges; at least one edge has electric insulating section of preset width; specific electrical resistance of this section is lesser than electrical resistance of central section by 5 times.
EFFECT: reduced usage of materials; continuous operating cycle; improved quality of cathode metal.
