ELECTROCHEMICAL METHOD OF CLEANING AQUEOUS SOLUTIONS OF COPPER FROM MANGANESE Russian patent published in 2003 - IPC

Abstract RU 2209839 C2

FIELD: extraction of substances by electrical extraction method; ferrous and non-ferrous metallurgy; domestic runoffs. SUBSTANCE: selective extraction of copper from solutions containing manganese is effected by electrical extraction from sulfate and chloride sulfate solutions at separation of metallic copper on titanium cathode and sedimentation of manganese in composition of anode sludge formed on lead anode. Proposed method enhances cleaning of copper from manganese improving quality of cathode copper and waste-free technology. EFFECT: enhanced efficiency and ecological safety. 6 tbl
