Separation and Recovery of Useful Metals in Waste Lead-Free Solders Using Iron Chloride Solution |
| abstract |
The present invention relates to a method for separating and recovering a useful metal from a waste lead-free solder using an iron chloride solution. The useful metal separation recovery method in the waste lead-free solder using the iron chloride solution according to the present invention includes a waste lead-free solder containing tin, copper and silver, and a solubility enhancer for enhancing the solubility of trivalent iron ions, tin and copper. Solvent in which solid silver and liquid tin ions and copper ions are dissolved through a leaching step of leaching tin and copper from the waste lead-free solder and precipitating silver from the lead-free solder, and solid-liquid separation after the leaching step. It comprises a solid-liquid separation step of separating each other and a selective recovery step of separating and recovering copper and silver from the solvent. |
