Beschreibung
Zusammenfassung:	The invention relates to a treatment method of metal sludge. The method comprises the steps of dissolving metal sludge into a first acid solution to form a first compound containing first metal cation and first acid anion; extracting the first compound so as to enable a resin material to be reacted with the first compound to form metal ions and a second acid solution; replacing the metal ions, enabling a third acid solution to be reacted with the metal ions to form a second compound containing second metal cation and second acid anion, wherein the concentration of the third acid solution is greater than that of the second acid solution; electrolyzing the second compound to form a metal.
