Abstract
An arrangement for spacing electrodes used in the electrowinning of copper includes two identical spacers which are designed to be mounted in an opening of an anode. Each spacer is elongated and has two ends which respectively face upward and downward during use. The upward facing end includes a confining surface which confronts a major surface of the anode on which the spacer is mounted and a sliding surface which faces away from the confining surface and has a slope. The confining surface and the sliding surface meet at a knife-edge which again faces upward during use. When the anode on which the spacer is mounted is immersed in an electrolytic bath and a cathode is lowered into a position adjacent to the anode, the knife-edge prevents the cathode from becoming caught on the spacer should the cathode be lowered onto the spacer. In addition, the sliding surface allows the cathode to slide towards its position. The two spacers have cooperating parts at their downward facing ends for locking the spacers to one another.
