Abstract

Способ электролитического рафинирования меди в блок-сериях ванн ящичного типа, включающий электролиз с растворением анодной меди и осаждением катодной меди при воздействии электрического тока с катодной плотностью тока 220-330 А/м, прямоточную подачу раствора при скорости циркуляции от 12 до 30 дм/мин, с концентрацией свободной серной кислоты 120-180 г/дм, с температурой 50-65°С и заданным коллоидным режимом, отличающийся тем, что концентрация меди в сернокислотном растворе поддерживается в пределах 35-65 г/дм, при напряжении на ванне 0,25-0,6 В, а суточный выводимый объем раствора из блок-серий ванн составляет 1-4,% от общего объема и восполняется конденсатом или медесодержащим раствором.Method for electrolytic refining of copper in block series of box-type baths, including electrolysis with dissolution of anode copper and deposition of cathode copper when exposed to an electric current with a cathode current density of 220-330 A / m, direct-flow solution supply at a circulation rate of 12 to 30 dm / min , with a concentration of free sulfuric acid 120-180 g / dm3, with a temperature of 50-65 ° C and a given colloidal regime, characterized in that the concentration of copper in the sulfuric acid solution is maintained within 35-65 g / dm3, with a voltage on the bath 0, 25-0.6 V, and the daily withdrawn volume of the solution from the block series of baths is 1-4,% of the total volume and is replenished with condensate or copper-containing solution.
