METHOD OF ELECTROLYSIS OF AQUEOUS SOLUTIONS OF METALS Russian patent published in 2000 - IPC

Abstract RU 2145983 C1

FIELD: electrochemical technologies. SUBSTANCE: solution of metal sulfates saturated with sulfur dioxide is subjected to electrochemical treatment at excessive pressure of 0.3 MPa. During electrolysis, sulfur dioxide hydrolysis products are oxidized on graphite anode forming sulfuring acid. Metal settles on anode. Anode potential is shifted to area of potentials which are lesser positive as compared with oxygen extraction potential. EFFECT: increased current efficiency at low power requirements. 4 ex
