Abstract
In a method of continuously casting unrefined electrodes in quantity for use in the electrolytic refining of metal in which a metal e.g. copper, strip is continuously cast and cut at spaced positions along its length to form electrodes, a substantial saving in metal is effected by casting the strip in such a way that, in longitudinally spaced minor portions of its length, the strip has at least one hole, recess in at least one of its side edges, or region of substantially reduced thickness as compared with that of the major portion of its length. When the strip is cut each electrode has, in that portion of the electrode that will protrude above the level of the electrolyte solution when the electrode is supported in an electrolytic cell, at least one hole, re-entrant in an edge of said portion, or region of substantially reduced thickness as compared with that of the main body of the electrode, the area of said hole, re-entrant or region constituting a substantial proportion of said protruding portion of the electrode.
