Here is some info supporting the use of chlorides to separate most metals and rare earths from a slurry waste stream at low temperatures.

United States Patent
December 18, 1979
Process for making rare earth metal chlorides

Forgive the question, but has this anything to do with chlorides fast breeders often cited in this site or it' s a totally different process that can be eventually implemented both in fluoride and chloride reactors ?

No problem, it’s my privilege.

This invention is inspired and directed toward the mining and purification of various minerals as far as I can tell. The inventor specialized in this.

For you information, the assignee of the patent is the Cato Corporation. Currently, Cato Research Corporation is a full-service contract research and development organization with international resources dedicated to helping pharmaceutical and biotechnology companies efficiently and expeditiously navigate the regulatory approval process in order to bring new drugs, biologics, and medical devices to the people who need them.

What Cato Corporation did back in 1977, I do not know.

Can it eventually be implemented both in fluoride and chloride reactors? I hope so, if there is a good fit of course.

The old Zenith slogan: The quality goes in before the name goes on.

Just curious, aren't these, previously cited in an other thread, better ? Or, which are the main differences between these different processes ?

According to ORNL vapor pressure curves from various fluorides: ... L-3791.pdf

CsF is much more volatile than BeF2 under a hard vacuum, and the reverse is true at atmospheric conditions.

I was wondering if we can use this fact to remove CsF in another small vacuum distillation unit that operates at much lower temperatures, so that BeF2, UF4 and LiF stay in the still bottoms but CsF is removed. A tad of BeF2 might still (pardon the pun) come along with the CsF but that's no disaster.

It would be great if this step can be combined with a ZrF4 sublimation trap so Zr is removed as well.
