| titleOfInvention | A kind of method of gold-tin alloy separation |
| abstract | The present invention relates to a kind of methods of gold-tin alloy separation, belong to non-ferrous metal field of thermometallurgical technology.Gold-tin alloy is put into closed container after mixing with vulcanizing agent and is sealed, vulcanization reaction is carried out under anaerobic, stirring condition, the tin in gold-tin alloy is vulcanized as stannous sulfide.Material is evaporated in vacuo under certain condition after vulcanization, and stannous sulfide is made to volatilize, to realize the separation of gold and tin.Present invention process process is short, and gold-tin alloy is i.e. separable by vulcanizing and two processing steps being evaporated in vacuo. |
