I recycle metal (gold. Silver and palladium) from pcb by hydrometallurgy process.
Before i dismantled component from pcb with air hummer. But now i decided chemically by organic solution like alkane sulfonic acid and glycol ether selectively dissolve solder. And then use electrowinning to separate solder from solution . Given that reduction potential of tin and lead closer together.
Is it possible to separate tin and lead by electrowinning?
How is doing this?
