Member Info for ReeTech

I doubt that Europe will agree to the export of concentrate to the United States. This is possible only in "banana" countries.

For information:

after leaching of phosphogypsum, to reduce its acidity, washing of phosphogypsum is necessary - water consumption is 500 liters per 1 ton.

How do you plan to dispose of the wash water?

I can only wish you good luck and faith in a "bright" future!!!

Unlike Phalaborwa, where phosphogypsum is obtained from the processing of apatite, an igneous rock, in Morroco, phosphorites are mined and processed - jigging rocks with a low, very low REE content. This is confirmed and proven by many geologists in the world. It is apatite, and not phosphorite, that has a significant REE content. And to say that in Morocco the numbers are very similar to Phalaborwa is at least not correct.

Moroccan phosphogypsum has a very low REE content, more than 20 times lower than South African.

And it is unlikely that its processing will be profitable.

The studied PG samples were collected from a Moroccan phosphate treatment plant.

Chemically, the PG samples were mainly composed of Ca (23.03–23.35 wt.%), S (17.65–17.71 wt.%), and Si (0.75–0.82 wt.%), and non-negligible amounts of trace elements: REE (344–349 ppm), Cd (3.5–7.4 ppm), U (9.3–27.4 ppm). Mineralogically, the PGs are mainly formed by gypsum (94.2–95.9 wt.%) and quartz (1.67–1.76 wt.%).

I do not want to disappoint you, but the REE content in gypsum,%:

- Tunisia - 0.022

- Morroco - 0.035

- Florida - 0.034

Data on the content of NdPr in Moroccan gypsum stacks are not something new, all data are known and published for a long time. The NdPr content in Moroccan stacks is ten times less than Phalaborwa.

"The PEA and DFS are what they are and agreements follow."

How far have the implementation of these agreements been?

A year has already passed since they were signed.

"The price is determined by what the customer is willing to pay. George has said that the customers are willing to go to 60% Payability for our sulphate, hence the renewed interest in selling sulphate as an intermediate step.

The second PEA will identify the Payability and capex/opex of this route.

We have a irrelevant level of radioactivity, as has been proven in tests."

You can talk and write a lot about "beautiful" PEA, but more convincing are the protocols for the chemical composition of mixed rare earth sulphate, as well as signed agreements with the buyer.

We didn't see any of this.

The price of the concentrate does not depend on whether it is sulfate or carbonate. Price depends on REE content and content of radioactive and toxic elements.

I want to say that the cost of mixed rare earth sulphate will be $ 5600 - 20-30%.

Therefore, RBW decided to build a plant for the production of individual oxides REE.

The informal chemical symbol Ln is used in general discussions of lanthanide chemistry to refer to any lanthanide.

Please read -https://en.wikipedia.org/wiki/Lanthanide#:~:text=The%20lanthanide%20(%2F%CB%88l%C3%A6,71%2C%20from%20lanthanum%20through%20lutetium.

The sum is mathematically denoted by the capital Greek letter Σ (sigma).

A typical mixed rare earth sulphate made from phosphogypsum has a ΣLn2O3 content of 25-30%.

One ton of mixed rare earth sulphate derived from Phalaborwa phosphogypsum (based on "Table 7.9: Typical PLS Stream Composition") will contain:

Nd2O3 - 5-7%, i.e. 21kg

Pr2O3 - 25-27%, i.e. 81kg

For a total of $7140.

The actual cost of mixed rare earth sulphate will be lower, since the content of ThO2 is 1.5-2.0%, which will affect the radioactivity over 500 Bq/kg

This project is still alive?

Or did it all end with the signing of the Master Agreement?

The sum is mathematically denoted by the capital Greek letter Σ (sigma).

A typical mixed rare earth sulphate made from phosphogypsum has a ΣLn2O3 content of 25-30%;

Carbonate concentrate REE ΣLn2O3 42-45%

We are waiting for the results of the pilot plant and the chemical composition of the resulting mixed rare earth sulphate.

Prices for REE are far from $100

Rare earth oxide content 42.0-45.0%

Praseodymium oxide content 99.0-99.9%

Neodymium oxide content 99.0-99.9%

As I understand it, you figured it out and counted.

Report chemical composition data for RBW sulfate concentrate.

Any data on the chemical composition of the concentrate?
