Separating and recycling method for nickel-plated copper wire

The invention provides a separating and recycling method for a nickel-plated copper wire. The separating and recycling method comprises the steps that firstly, plastic skin on the surface layer of thenickel-plated copper wire is separated, and the plastic skin is put into a vacuum pyrolysis reaction device to be pyrolyzed; secondly, the nickel-plated copper wire of which the plastic skin is stripped is cut by a copper graining machine to be converted into nickel-plated copper grains; thirdly, the obtained nickel-plated copper grains, steel balls and medium oil are mixed according to a certainproportion and subjected to ball milling treatment, cleaning and screening are conducted by adopting alcohol, and nickel-removed copper grains and a nickel and copper powder mixture are obtained; andlastly, the nickel and copper powder mixture is put into diluted hydrochloric acid for a reaction, filtering is conducted, and a nickel chloride solution and copper powder are obtained. According tothe separating and recycling method for the nickel-plated copper wire, separating and recycling treatment is conducted in a targeted mode according to the physicochemical characteristics of the plastic skin of the nickel-plated copper wire, copper and nickel, the whole recycling process is clean and has no pollution, and the recycling rate is high.
