Polypropylene plastic baskets for phosphorized or non-phosphorized copper anode nuggets are suspended, one on each side of a cylinder to be plated, in a bath of plating electrolyte. The tops of the baskets are disposed beneath the surface of the plating solution, the upper portion of the cylinder is above the surface of the electrolyte, lead anode conductor strips extend downwardly along the insides of the rear walls of the baskets, and the front walls of the baskets are perforated. When the cylinder is printed out, it is returned to the plating apparatus and reversably plated so as to return the copper to the nuggets. In order to prevent the copper from building up through the perforations in the inner walls of the baskets, a porous plastic sheet is disposed over the inner surface of the inner walls of the baskets.
