METHOD AND REAGENT FOR RECOVERING RARE/INERT METALS FROM BOTTOM ELECTROPLATING COPPER/NICKEL MATERIA

A method for recovering rare/inert metals from a bottom electroplating copper/nickel material. The method comprises the following steps : (1) pretreatment; (2) preparation of a rare/inert metal removal solution : adding an additive No.1 that is mainly used for complexing and an oxidizer into an inorganic acid water solution to prepare the rare/inert metal removal solution, and heating the rare/inert metal removal solution to 50°C to 70°C; (3) oxidation and complexing of a copper/nickel coating : immersing a dried electroplating material in the rare/inert metal removal solution, and standing until the rare/inert metal foil is thoroughly removed from the surface of the electroplating material base; and (4) filtration and drying to obtain the rare/inert metal foil. Also provided is a reagent for recovering rare/inert metals from a bottom electroplating copper/nickel material. By means of the method and the reagent, the recovery rate of rare/inert metals can reach 98% or more.
