FIELD: electrics.
SUBSTANCE: invention relates to electrolysis method and to electrolytic agent used to extract metal from water solution. Method includes the stage dealing with current of non-uniform density generation along collecting surface so that sections with high current density could be generated together with low current density sections in alternating manner. Difference between high density sections and low density sections is sufficient to cause metal deposition concentrating in high density sections to facilitate non-uniform metal deposition on surface. Electrolytic agent contains cathode with collecting surface where metal is deposited during water solution electrolysis. Electric field of cathode collecting surface is not uniform. It has sections of strong electric field alternating with weak electric field sections due to creation of ordered set of alternating ridges and hollows. Ridges form strong electric field sections while hollows form weak electric field sections.
EFFECT: facilitation of metal deposition removal.
