Abstract The present invention relates to an insoluble anode for the electrowinning of heavy metals from aqueous solutions which contain them, and for the electrolytic production of oxidizer halogenated salts. The anode is constituted by a copper bar acting as a bus bar (i.e., as a current-bearing bar), provided with vertical and horizontal holes through which fork- shaped elements, made from a bimetallic conductor, are inserted and fastened; by a plurality of fork-shaped elements, made from said filamentary bimetallic conductor, coated by a catalytic layer of Pt and/or PbO2, acting as an electrode with preferential oxygen development; by a framework made from an insulating plastics material, which is used to support and stiffen the structure, and for the precise positioning of the anode inside the cell.
