Abstract
An electrode assembly for the electrowinning of copper includes an electrode in the form of a plate. An edge strip is mounted on one edge of the electrode and serves to mask the edge from an electrolyte in which the assembly is immersed. A gap exists between the edge strip and the electrode on either side of the electrode. A sealing strip is located in each gap, and the sealing strips are discrete from the electrode and the edge strip. The sealing strips are resilient and can be stretched to remove the sealing strips from the gaps so that the sealing strips can be replaced.
