Low temp distillation of metals

Click For Summary
SUMMARY

Fractional distillation methods are impractical for separating metallic elements with low boiling points, such as mercury (Hg) and zinc (Zn), due to their similar chemical properties. However, liquid metal distillation may be applicable in specific scenarios, such as the separation of bismuth (Bi) and lead (Pb). The discussion highlights the potential use of vacuum distillation for refining steel scrap and references relevant studies, including a photographic study on liquid metal distillation and the separation of polonium-210 from bismuth.

PREREQUISITES
  • Understanding of fractional distillation techniques
  • Knowledge of low boiling point metallic elements
  • Familiarity with vacuum distillation processes
  • Basic concepts of pyrometallurgy
NEXT STEPS
  • Research the principles of vacuum distillation for liquid metals
  • Explore the separation techniques for bismuth and lead
  • Investigate the role of pyrometallurgical methods in metal refining
  • Study the applications of fractional distillation in metallurgy
USEFUL FOR

This discussion is beneficial for metallurgists, chemical engineers, and researchers involved in metal refining and separation processes.

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.
 
Engineering news on Phys.org
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.

See if this works -

I also know that certain pyrometallurgical techniques have been proprosed for metal fuel used in the integral fast reactor (IFR), but offhand I don't recall the process.
