i need your help.
I had some solder that was like 45% silver and the rest tin and copper i think. I wanted to make a big coin to hammer flat to make some squares to practice engraving.
I attempted to melt that solder and some actual tin solder together to make a big ingot and try to stretch the silver out, but it made a big brittle coin.
Now I want to try and get the silver back out of it without the tin, having come to the realization that this wont work.
I read that HCl might dissolve the tin and leave the silver.
What im asking is, what combination of acids or methods would easily get the silver out of this.
thanks.

nobody on /sci/ has any practical skills or abilities, try /diy/

They use hydrolic presses.

Not a Chemist, sorry.

Get a propane torch, a small crucible, and a pair of tongs. Heat the coin directly with the flame until it melts. Since silver is most dense, it would sink to the bottom. Carefully pour out the tin/copper in a coin mold.

That's not going to work

I have hammered copper and discovered early that it gets brittle fast so one needs to heat it frequently to get it back to normal status. Its called work hardening.
