Prior to the development of the Isa Process technology, the standard approach was to use a starter sheet of highpurity copper as the initial cathode. These starter sheets are produced in special electrolytic cells by electrodeposition of copper for 24 hours onto a plate made of copper coated with oil (or treated with other similar faceseparation materials) or of titanium.
