How to Recover Tin, Copper & Lead from their chlorides

[Goldextraction32]

I have a solution that contains chlorides of tin, lead and copper.
How can I recover all the three metals from them?
Please help!

Well, you could cement all three to zinc.
Iron may work, except it is close to tin in reactivity.
Before cementing you could try separating the lead with an addition of sulfuric.

Thanks for your reply. But if I use zinc it will precipitate both tin and copper. Then how to separate them from each other? Can't there be a chemical process that can precipitate these metals separately?
Thanks!
