    Characterization of Tin-rich Copper Anodes from Secondary Copper Refineries

    By T. T. Chen

    Copper anodes generated from copper scrap are relatively rich in Sn, Zn and Fe. Because of the presence of oxygen, only trace amounts of Sn occur in solid solution in the copper crystals. Thus, Sn occ
