  • Method for repairing nickel-zinc-copper or nickel-zinc alloy electroplating solutions from acidic waste solutions containing nickel and zinc ions and electroplating thereof
    Patent number: 5888373
    Abstract: A method for preparing a nickel-zinc-copper or nickel-zinc alloy electroplating solution from at least one electroplating waste solution and/or at least one acidic leach solution of metal scrap containing nickel and/or zinc ions is disclosed. The method involves mixing two or more than two of solutions of the electroplating waste solutions and the acidic leach solutions, and optionally water, so that the ion concentrations of Ni, Zn, Cu, Fe, Cr and Pb of the resulting mixed solution are within the following ion concentrations:15 gdm.sup.-3 <Ni.sup.2+ <58 gdm.sup.-3, 28 gdm.sup.-3 <Zn.sup.2+ <44 gdm.sup.-3, 0<Cu.sup.2+ <1430 gm.sup.-3, 0<Fe.sup.2+ +Fe.sup.3+<5000 gm.sup.-3, 0<Cr.sup.3+ <1000 gm.sup.-3 and 0<Pb.sup.2+ <50 gm.sup.-3.
