Abstract

A coated metal anode for the electrolytic recovery of metals is disclosed, whereby the working surface of this anode is represented by rods 4 which are arranged in a plane in spaced, parallel relationship to each other and which are electrically connected to a current supply rail 3. To provide a coated metal anode of the identified type, which ensures an operation with acceptable current density and which permits with a simple constructive assembly an energy saving deposit of metal with high purity on the oppositly disposed cathode, the total surface F.sub.A of the rods 4 and the surface F.sub.p assumed by the total arrangement of the rods 4 fulfills the relationship 6.gtoreq.F.sub.A :F.sub.p .gtoreq.2.

Dependent claims

A coated metal anode for the electrolytic recovery of metals, the working surface of which is represented by rods which are arranged in a plane in spaced, parallel relationship to each other, and which are electrically connected to a current supply rail, wherein:

said rods lie in a plane with the current supply rail, so as to create a substantially planar rectangular, surface of the anode;
said rods being arranged in such a manner that a larger portion of the area of said rods extends perpendicular to the arrangement plane assumed by said rods than is congruent with said plane;
and
said rods are connected to said current supply rail at one end face;
and
both the electrical and mechanical connection of each rod with said current supply rail takes place by means of at least one connecting strip extending parallel to said rod;
and wherein
one marginal region of said connecting strip is connected with said current supply rail and another marginal region is connected with said rods.
