# Low temp distillation of metals

Is practical to employ fractional distillation methods on a mixture of two metallic elements with low BP - for example Hg and Zn?

And no, I'm not trying to do this.

Zn and Hg are in the same group, so they may not be effective.

Liquid metal and distillation may be possible in a few limited cases.

It might be possible with Bi-Pb, but I don't remember.

This is more to do with removing impurities for refining steel scrap.
