| titleOfInvention | A kind of method that reclaims valuable metal from waste and old nickel-zinc cell |
| abstract | The invention discloses a kind of method that reclaims valuable metal from waste and old nickel-zinc cell. Said method comprising the steps of: waste and old nickel-zinc cell is placed in to saturated aqueous common salt and carries out self discharge processing; Self discharge nickel-zinc cell after treatment is carried out to crushing and screening and obtain oversize and screenings; Oversize magnetic separation is obtained to scum and namagnetic substance; Namagnetic substance and screenings are mixed, then by mixture sulfuric acid leaching, obtain after filtering leachate; Leachate, by chemical Treatment and extract and separate, is obtained to nickelous sulfate cobaltous sulfate binary liquid mixture, zinc solution and calcium chloride solution, or nickelous sulfate cobaltous sulfate binary liquid mixture, zinc solution, copper salt solution and calcium chloride solution; By concentrated, crystallization and the centrifugation respectively of above-mentioned solution, complete the recovery of valuable metal. The inventive method can not produce secondary pollution to environment, and technological process is short, and resource recycling rate is high, handicraft product selects flexibility strong, with low cost, has higher economic benefit. |
