A plating product fabrication method includes forming a first concentrate. The concentrate includes a Tin (Sn) species and a trace amount of Polonium (Po) species. The plating product fabrication method also includes creating a circuit between a filtering anode and a filtering cathode and reducing the Po species from the concentrate by plating Po upon the filtering cathode. In this manner, a purified Sn concentrate is formed. The purified Sn concentrate may be utilized to plate Sn upon a plating cathode. The purified Sn concentrate may be utilized to form purified Sn.
