摘要

In the past a lot of investigations were done to increase the current density in copper electrolysis. At present the highest used average current density is in the range of 330 - 350 A/m~2. But current density figures of single cathodes in one cell are from lower than 200 A/m~2 to more than 600 A/m~2. The reasons for that are irregular geometrical conditions of the electrodes and bad electrical connections. Cathodic copper deposits were measured in dependence of the distances between the electrodes. The standard experiment was done with parallel distance between anode and cathode. For further experiments the cathodes were canted, bent and different distances were chosen. Afterwards the current density distribution on the cathodes was calculated.
