Frances Wall, Professor of Applied Mineralogy at the Camborne School of Mines (CSM), University of Exeter, University of London, UK: "Problems in the processing of rare earths- the importance of mineralogy"
This is a deception, which has become a classic. You can read about it here
However, on all sites that I have at, it says "Synchysite is a group of carbonate mineral. Apatite is a group of phosphate minerals".
Frances Wall, Professor of Applied Mineralogy at the Camborne School of Mines (CSM), University of Exeter, University of London, UK: "Problems in the processing of rare earths- the importance of mineralogy"
They write: "The diverse mineralogy of alkaline rocks has required development of processing routes for rare minerals such as steenstrupine and eudialyte"
Eudialyte typically has a significant content of uranium. This means it is radioactive.
Steenstrupine and eudialyte are radioactive.
What is the advantage of steenstrupine and eudialyte? The answer is obvious, that no.
2. Steenstrupine contains 27 % REE (Ce). eudialyte contains 10 % REE.
You can not sell what poor concentrate!
Monazite contains 70 % REE. Bastnaesite contains 75 % REE.
What is the advantage of steenstrupine and eudialyte? The answer is obvious, that no.
3. They do not have technology for processing steenstrupine and eudialyte
The development of technology can take dozens of years.
What is the advantage of steenstrupine and eudialyte? The answer is obvious, that no.
Technologies for the processing of monazite and bastnaesite exist (They need to be improved).
4. Prominent localities of eudialyte include the Kola Peninsula in Russia, Greenland (Norway, Canada).
Prominent localities of steenstrupine include the Kola Peninsula in Russia, Greenland.
What is the advantage of steenstrupine and eudialyte? The answer is obvious, that no.
A harsh climate, remoteness creates additional costs.
Prominent localities of monazite:
5. There are more than 110 minerals containing the Cerium (Ce). 40 of them contain more Cerium than Steenstrupine. Why Steenstrupine?
6. They offer us to extract the cerium mineral - Steenstrupine. Cerium is enough.
In the world there is a shortage of these REE: Y, Dy, Nd, Eu, Tb, but no Ce.
The increase in production volumes La, Ce leads to lower prices for these metals.

They write: " A deposit with two ore minerals, REE fluorcarbonate and apatite"
1. Fluorcarbonate is not a mineral, it is a mineral group.
2. Apatite does not form REE deposits.
This is a deception, which has become a classic. You can read about it here
Can you share what classification of minerals do you use?
You write that "The fluorcarbonate (synchysite) - apatite".However, on all sites that I have at, it says "Synchysite is a group of carbonate mineral. Apatite is a group of phosphate minerals".
