I posted this on another thread, I am not trying to cross promote, but to me it does relate to REE and perhaps what FMG see in the deposits that TAS hold, and maybe that relates to how the US is looking at REE and the importance to their own Industrial Base!
Nursery, please take note about what is said with respect to REE processing!
I really can't stress enough the importance of lasers to this!
It perhaps maybe may not be related to Silex, but to my mind it fits perfectly?
I have been wrong before, and I may well be wrong here,and yes I will be wrong again at some point in the future, but I like to keep an open mind!
I can't say for sure that Silex are working on this? but they did hint that there may be other Isotopes they are looking at with their stable Isotope separation besides the ones they originally talked about?

Highlights•
This paper presents an update on all aspects of REE including their distribution in the Earth's crust, impact on environment, and human health.
•
Other aspects covered include different types of deposits, metallurgy, applications in agriculture and
medicine, and recycling.
•
An outline of the recent advances in their precise determinations required in all these studies is also presented.
•
This is the most comprehensive review attempted on REE so far in the literature.
AbstractRare earth elements (REE) include the lanthanide series elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. Currently these metals have become very critical to several modern technologies ranging from cell phones and televisions to LED light bulbs and
wind turbines.
This article summarizes the occurrence of these metals in the
Earth's crust, their
mineralogy, different types of deposits both on land and oceans from the standpoint of the new data with more examples from the
Indian subcontinent.
In addition to their utility to understand the formation of the major Earth reservoirs, multi-faceted updates on the applications of
REE in agriculture and medicine including new emerging ones are presented.
Environmental hazards including human health issues due to REE mining and large-scale dumping of e-waste containing significant concentrations of REE are summarized.
New strategies for the future supply of REE including recent developments in the extraction of REE from coal fired ash and recycling from e-waste are presented.
Recent developments in individual REE separation technologies in both metallurgical and recycling operations have been highlighted.
An outline of the analytical methods for their precise and accurate determinations required in all these studies, such as, X-ray fluorescence
spectrometry (XRF),
laser induced breakdown spectroscopy (LIBS), instrumental
neutron activation analysis (INAA), inductively coupled plasma optical emission spectrometry (ICP-OES),
glow discharge mass spectrometry (GD-MS),
inductively coupled plasma mass spectrometry (including ICP-MS, ICP-TOF-MS, HR-ICP-MS with
laser ablation as well as solution nebulization) and other instrumental techniques, in different types of materials are presented.
