Beschreibung
Zusammenfassung:	A diaphragm element of a cell for electroextraction of metals from aqua solutions and a method of manufacturing the diaphragm element are disclosed. A diaphragm ele-ment is formed from a diaphragm fabric and comprises at least one side surface with vertical edges and horizontal edges, wherein at least one edge of at least one side surface of the diaphragm element is formed with an electrically insulating edge portion having a predetermined width and specific electrical resistance of at least 5-fold compared to the specific electrical resistance of the middle portion of the side surface. The invention ensures reduced material and labor costs for manufacture and operation of diaphragm cells of electrochemical reactors, provides disturbance-free production cycle, and improves quality of the cathode metal.
