Valuable forum members,
It is necessary to completely remove the Sn / Pb alloy solders before starting an efficient refining process. I'm undecided about which method to use for this.
1. Idea: Rams and Cell mobile phone boards demolish with hot HCL (without boiling). But how long does this process take and any PM loss?
2. Idea: adding 35% or 50% H2O2 in small amounts to 50% NaOH solution.
How do I recover the solved tin and lead? Which method is better in this regard?
Thank you very much for your help already.
Sorry, my English is not very good.
Best Regards,
Mehmet
