　　Silver as a highly conductive metal is usually doped in YBa2Cu3O7-x superconductor bulks to improve the critical current density of YBa2Cu3O7-x superconductor.The valuable metal elements silver, yttrium, barium and copper in waste YBa2Cu3O7-x/Ag composite superconductor bulks were recovered respectively.Silver was recovered with the process that first, the waste was dissolved by nitric acid and silver chloride was precipitated by adding chloride acid, then silver pig was obtained by melting silver chloride together with sodium carbonate at 1000℃.
