ABSTRACT:
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 perforate.
After the cylinder is printed out, it is returned to the plating apparatus and reversely plated to remove the copper. In order to prevent the copper from building up through the perforations in the inner walls of the baskets and to keep reduced-size nuggets from protruding through the basket openings, a porous plastic sheet is disposed over the lower portion of the inner surface of the inner wall of each of the baskets. Between the baskets and the cylinder titanium screens are placed over the inner walls of the baskets and are in contact electrically with the lead anode conductor strips so that copper from the cylinder plates onto the screens.
