Member Info for ReeTech

Mineral composition and identification of REE-containing minerals are of great importance in assessing the economic potential of phosphogypsum. SEM, EPMA, ICP-MS/AES based studies and analyzes are used to identify REE-bearing minerals. Phosphogypsum Uberaba consists mainly of gypsum crystals, making up about 93% of the total mass. Accessory minerals are quartz, REE-containing fluorides (Ca-, Al-), monazite, celestine, iron oxides, ilmenite, barite, pyrochlore and baddeleyite. Monazite is the most important REE carrier in phosphogypsum. The total REE content in monazite averages 57%. Monazite contains 50% to 60% of the total REE in phosphogypsum, with the remaining 40-50% contained in gypsum and Ca-Al fluorides. Therefore, no more than 40-50% REE can be extracted from phosphogypsum, which is less than from Phalaborwa phosphogypsum - ABOUT 65% (this is declared by RBW).

We are waiting for the results of mineralogical analysis of Uberaba phosphogypsum.

I would really like to see a chemical analysis of the mixed rare earth sulfate with a content of 58%.

In addition, I would like to receive at least some information on the “dead” projects in Morocco and the extraction of REE from nitrophosphorus solutions in South Africa, the information has disappeared even on the RBW website)))))

"The processing of the gypsum stacks will remove much of the radioactive element and makes the stacks safe to sell as building materials. One of the many benefits of the RBW/Ktech process."

....and are concentrated in a mixture of rare earth sulfates.

I'm looking forward to the analysis report (from an accredited laboratory) of Phalaborwa mixture of rare earth sulfates.

In Brazilian phosphogypsum, a large proportion of REE is contained in monazite. This has been confirmed by many studies.

Leaching monazite is difficult because it requires high temperatures and concentrations of sulfuric acid. In addition, monazite has a high content of radionuclides, decay products of Th (thorium) and U (uranium), such as Ra-226, -228, Pb-210, K-40.

"Initial assay analysis from samples indicates an average grade of 0.58% total rare earth oxides ("TREO"), higher than the 0.44% TREO for the Phalaborwa project." - great results!

"Rainbow is encouraged by these results and is therefore planning additional test work at SGS around the mineralogy to identify the rare earth phases and facilitate the development of a process test programme."

The main thing to pay attention to is precisely - "mineralogy to identify the rare earth phases".

Gypsum processing tailings are monazite-containing phosphogypsum of the ultrabasic alkali-carbonatite complex. Published articles on the mineralogy of Uberaba phosphogypsum indicate that REE is mainly contained in MONAZITE, the opening of which is difficult!

In addition, an article on radionuclide content raises a number of questions - https://www.radioprotection.org/articles/radiopro/abs/2002/05/rad20021pC1-1307/rad20021pC1-1307.html

"Where you studied, I taught"))))

I regret it!

Your calculations are taken from nowhere - it's a scam!!!!

Tell me - what is the cost of mixed rare earth sulphate?

Without knowing the content of Nd, Pr, Dy, and Tb )))))))

Analysis of the chemical composition indicating the content of rare earth elements (Nd, Pr, Dy, and Tb) will allow you to calculate the price of the obtained mixed rare earth sulphate.

Hopefully we'll see an accredited lab's chemical analysis protocol.

What is the content of Th (thorium) and other impurities in mixed rare earth sulphate?????

Beautiful photos)

I would like to see the chemical analysis protocol of an accredited laboratory.

In Russia, in the Moscow region, the Skygrad Innovations enterprise will launch production for the processing of phosphogypsum to produce gypsum stone and a concentrate of rare earth metals. Currently, equipment is being installed and commissioned at the site in Voskresensk. The first stage of the plant is planned to be launched at full capacity in the third quarter of 2024.

The first stage of work will take place at the plant in Voskresensk, then the raw materials will go to the enterprise in the Korolev technopark. At the first stage, phosphogypsum will be washed from water-soluble impurities. On the second - processed with sulfuric acid. This will make it possible to obtain white gypsum and sulfuric acid solutions, from which rare earth metals will be extracted in the future. Phosphogypsum dumps in Voskresensk are waste products from the production of the Voskresensk Mineral Fertilizers plant. The main task of the new enterprise will be the processing of waste into useful raw materials.

To date, Skygrad Group of Companies is the only company in Russia that produces individual rare earth compounds from concentrate, such as oxides and carbonates of cerium, neodymium and lanthanum.

The production capacity of the enterprise at the first stage will allow to process about 60 thousand tons of phosphogypsum per year and produce about 180-200 tons of rare earth metal concentrate. In the future, the volume of processing will be increased.

The drop in the cost of NdPr oxide is more than 40%. Badly

However, grant money was also awarded more recently by Mosaic, the largest phosphate mining company in Florida.
