IIRC there's a whole forest of things, plus there's electrolytic refining as used for aluminium and a couple of other metals.

If you get into the history of metal refining it's kind of interesting, people have done a whole lot of things that are more than "dump in a charcoal furnace and see what happens".

For true insanity, turn it to plasma and fractionally distill that. I don't *think* that's actually done commercially.
