(54) СПОСОБ ЭЛЕКТРООСАЖДЕНИЯ(54) METHOD OF ELECTRIC SUPPLY
И РАФИНИРСЮАНИЯ МЕТАЛЛОВAND METAL REFINING
ной пол ризацией перемещаютс последовательно по периметру катода, то движение его поверхности слоев становитс посто нным . Это обеспечивает улучшение массообменных процессов на границе жидкометалли- j ческого катода и тем самым интенсификацию процесса электролиза. Непрерывность процесса электролиза при использовании пред лагаемого способа также способствует его интенсификации.Юpolarization is moved sequentially around the perimeter of the cathode, then the motion of its surface of the layers becomes constant. This ensures the improvement of mass transfer processes at the boundary between the liquid metal j cathode and, thus, the intensification of the electrolysis process. The continuity of the electrolysis process when using the proposed method also contributes to its intensification.
Можно также обеспечить неравномерную пол ризацию поверхности жидкометаллического катода последовательно по его пери- метру путем перемещени анода вдоль пе риметра катода.15It is also possible to provide an uneven polarization of the surface of the liquid metal cathode sequentially along its perimeter by moving the anode along the perimeter of the cathode.
Пример. Из электролита состава. г/л: Hjj00 (уд. вес. 1,84 г/см) 2Oj СиёО 5 HjjO 60; 20 -«-на жидкомртут ном катоде осаждают медь..При этом исполы зуют анод 3 виде медного стержн ,26Example. From the electrolyte composition. g / l: Hjj00 (spd. weight 1.84 g / cm) 2Oj SiOO 5 HjjO 60; 20 - "- copper is deposited on the liquid-mercury cathode. At this, anode 3 is used as a copper rod, 26
Способ осуществл ют по первой схеме (с несколькими анодами). Неравномерность пол ризации составл ет О,,3 В при времени цикла 1,3-2,6 сек и температуре 2О СThe method is carried out according to the first scheme (with several anodes). The non-uniformity of polarization is O ,, 3 V at a cycle time of 1.3-2.6 seconds and a temperature of 2 ° C
Величина предельного тока диффузии сое- 25 тавл ет 240-250 ма/см , тогда как дл известного способа она равна 15О ма/см .The magnitude of the diffusion current limit is 240-250 mA / cm, whereas for the known method it is 15O mA / cm.
Таким образом, предлагаемый способ поз вол ет интенсифицировать процесс электроли- за в 3,3 раза по сравнению с известным. зоThus, the proposed method makes it possible to intensify the electrolysis process by 3.3 times in comparison with the known method. zo
Пример2,В услови х примера 1, но при использовании второй схемы (с перемещением анода осаждают медь. При неравномерности пол ризации, равной 0,1-0,4 В, наблюдаетс вращательное движение поверхностных слоев ртути в направлении движени анода.Example 2, in the conditions of example 1, but using the second circuit (copper is deposited with the anode moving. If the polarization is uneven, equal to 0.1-0.4 V, rotational movement of the surface layers of mercury is observed in the direction of the anode movement).
Результаты опыта аналогичны приведен- ным в примере 1.The results of the experiment are similar to those shown in example 1.
П р и м е р 3. Из расплава 0,5%РЬС 2 на жидЛом свинцовом катоде осаждают свинец. Электролиз осуществл ют по первой схеме. Неравномерность пол риза-ч ции поддерживают в пределах 0,1-0,3 В, оптимальное врем цикла составл ет 2-5 сек. Достигнута интенсификаци процесса по сравнению с известным способом в 3 раза.PRI me R 3. Lead is precipitated from a melt of 0.5% PBC 2 on a liquid lead cathode. The electrolysis is carried out according to the first scheme. Polarity irregularity is maintained in the range of 0.1-0.3 V, the optimum cycle time is 2-5 seconds. Achieved intensification of the process compared to the known method 3 times.
