Copper and tin recovery from scrapped tinned copper materials could ease the shortage of copper and tin resources

providing good economic and social efficiency. The separation of copper and tin is the significant step of tinned copper materials recycling. Chemical method

electrochemical method

chemistry-electrowinning and pyrolysis method are introduced for the separation and recovery of copper and tin from scrapped tinned copper materials

providing reference for efficient recovery of copper and tin. Clarifying the composition of scrapped tinned copper could efficiently help find proper technology for the separation and recovery of copper and tin. Classification management should be strengthened when collecting scrapped tinned copper materials to avoid unknown impurities mixing

contributing to the highly efficient recovery of copper and tin.
