Hello,
I have around 2,5 kg of Lead Tin Silver and Lead Indium Silver alloys in the form of very small squares (5x5x0.2mm). 92.5% of Lead 2.5% of silver and 5 % of tin or indium depending on the version.
What would be the easiest way to recover silver?
The first idea was to use hot Hcl to dissolve lead tin and indium.
On YouTube I found a video of a guy separating silver from soldering wire using an electrolytic cell. In this case I would probably have to melt all the tiny pieces to have one big electrode.

Any other proposal?
