FIELD: extraction of valuable metals from super-alloys by electrochemical decomposition.
SUBSTANCE: super-alloy is used as both electrodes, anode and cathode. Electrochemical decomposition is realized at changing polarity of electric current with frequency 0.005 - 5 Hz while using non-organic acid as electrolyte.
EFFECT: possibility for extracting valuable metals in industrial scale, lowered cost of simplified extraction process, effective solution of part of metals, separation of metal groups.
