| titleOfInvention | A kind of recovery method of silver-coated copper wire |
| abstract | The present invention provides a kind of recovery methods of silver-coated copper wire, and silver-coated copper wire is cut into strip-shaped materials first, and by strip-shaped materials and steel ball, the processing of Medium Oil mixing and ball milling, screening obtains copper wire, steel ball and the Medium Oil for being mixed into silver powder, copper powder of removing silvering；The Medium Oil for being mixed into silver powder, copper powder is filtered to obtain the mixture of silver powder and copper powder；It feeds the mixture into dust technology and stands 5-7 days, sodium chloride solution is added into beaker, converts silver nitride precipitation for silver ion；Chlorination silver powder and copper nitrate solution is obtained by filtration；Obtained chlorination silver powder is added in the beaker for filling hydrochloric acid, enough zinc metal sheets are added, dark gray powder is obtained by filtration in heating stirring；Solid powder is put into crucible, using oxygen-butane flame blowtorch by the solid powder jet flames in crucible, carries out high melt, it is cooling, obtain silver bullion.Secondary pollution degree of the present invention is low, and the rate of recovery is high, industrialization recycling easy to accomplish. |
