Doing some research on the forum, it seems a decent amount of people have tried to extract tin from solder with little success. I've found that it
really isnt that hard just to electrolyze a solution of sodium chloride with a solder anode and copper cathode.
Lead chloride precipitates out leaving a stannous chloride solution which can be electrolyzed to form tin crystals.

You can also get lead free solders, many of which are substantially tin and contain only small amounts of other metals like copper and silver.

lead sulfate and chloride I believe are insoluble

Lead chloride is noticeably more soluble in solutions where there is already a high chloride concentration.

Lead will form complex ions with excess chloride, so some of it will stay in solution. The sulphate may be a better choice- it doesn't coordinate
nearly as well.

I did a tin-lead separation by dissolving solder in nitric acid. Lead went into solution as lead nitrate, and tin ended up in precipitate as, I think,
tin dioxide or stannic acid. Of course, it was actually lead I was after, and the dioxide was discarded.

My tin contains 99.3% Sn and 0.7% Cu. I wonder if it could be useful in any chemistry applications.
