How would you extract pure metals from ore in outer space?

There has been a lot of talk about mining asteroids in the last year or so and using the materials to build factories in space, but surely the techniques (not the chemistry) used in space would not be the same as on earth since there is no gravity.

ImminentFate is talking about a fractional distillation system.  A better way would be a gas centrifuge.  You still vaporize it but you run at the highest vaporization temperature of any of your materials.  You spin the vapor and the various atomic weights will settle to the places you have your output hoses set to.  Voila you have pure metals.

Yea it's not quite that easy but it's close.
