Abstract
An insoluble anode is for the electrowinning of heavy metals from aqueous solutions which contain them, and for the electrolytic production of oxidizer halogenated salts. The anode includes a copper bar acting as a bus bar (i.e., as a current-bearing bar), having vertical and horizontal holes through which fork-shaped elements, made from a bimetallic conductor, are inserted and fastened. A plurality of fork-shaped elements, made from the filamentary bimetallic conductor, coated by a catalytic layer of Pt and/or PbO.sub.2, act as an electrode with preferential oxygen development. A framework made from an insulating plastics material, is for supporting and stiffening the structure, and for the precise positioning of the anode inside the cell.
