ELECTROLYSIS BLOCK-SERIES OF BATHS FOR ELECTROLYTIC REFINING OF COPPER AND PROCESS OF ELECTROLYTIC REFINING OF COPPER Russian patent published in 2002 - IPC

FIELD: electrochemical production in non-ferrous metallurgy, electrolytic refining of non-ferrous metals, specifically, copper in aqueous solution. SUBSTANCE: electrolysis block-series of baths for electrolytic refining of non-ferrous metals, copper in particular, in aqueous solution of electrolytes comprises series of baths with multiple inclusion of electrodes in electric circuit and circulation of electrolyte supplied into each bath from one butt and discharged from the other butt. Each bath has several sections which electrode cells are placed in parallel in electric circuit and bathes are connected in series. Electrodes are arranged along each bath and rest against face walls of baths and electrode beams between sections laid on side walls of baths. Process of electrolytic refining of copper is carried out in baths of proposed design and is characterized by match of circulation directions of electrolyte and electric circuit with circulation velocity of electrolyte up to 50 cu. dm/min and voltage between 1 and 3 V across each bath of series. EFFECT: widened range of technical facilities employed for electrolytic winning, regeneration and refining of metals from solutions by electrolysis. 19 cl
