摘要

In the electrodeposition of metals in electrowinning and electrorefining processes, the current between end electrodes in a cell is generally higher than the average current between all electrodes in the cell thereby causing warping of the end electrodes, overheating of the electrical contacts at the end electrodes and a majority of the electrical shorts to occur at these end electrodes. These problems are alleviated by controlling the current between the first two and between the last two electrodes at a value that is not greater than the average value of the current between all electrodes in the cell, by increasing the lateral spacing between the end electrodes and their immediate neighboring electrodes.
