ABSTRACT:
The invention relates to a method for controlling or monitoring the quality of copper cathodes. The method is characterized by stacking cathodes to form a bundle, preferably comprising 10-20 cathodes, and by determining the bulk density, or a value related thereto, of the bundle. The bulk volume or mean height of a cathode bundle can be used with great accuracy. Advantageously, the height of each cathode bundle is measured by means of distance-sensing means of the laser or ultrasonic type placed above the movement path of a cathode bundle.
