Another failed attempt the emphasises RBW's game changing success.
Just stating facts, Donkey.
"So far, Mosaic officials havedeemed the steep capital and operating costs too high to justify beyond the lab and pilot scale. In a presentation to the U.S. Energy Association, the company reported the process is not yet economically viable “without significant government financial support, cooperative arrangement or other business incentives.”"
Florida will have to wait, Brazil is their current focus. RBW are working on lower concentration REE extraction with the Moroccan university
REE could double Mosaic's market cap, you bet they are in the business.
Don't worry Lewis, there is literally nothing to say about PRE and I cannot be bothered to reply to the idiot.
Look at linked in.
The team have designed/built a REE plant in Africa .
Read the RNS for the various companies who did the chemistry
So.. I now have to explain what a surprise is?
In the interview George expects a PEA FOR Umberaba this year.
Some more surprise news in a few weeks...
Linky?
Why don't you work it out yourself, or is the maths too difficult.
Yeas, there was, this is the SECOND pilot plant

Commencement of Phalaborwa Preliminary Economic Assessment
Rainbow Rare Earths Ltd is pleased to announce that work on the Preliminary Economic Assessment (the "PEA") for the Phalaborwa rare earths project ("Phalaborwa") in South Africa has commenced.
Independent test work carried out to date has confirmed that the phosphogypsum at Phalaborwa is amenable to direct leaching with sulphuric acid for extraction of the contained rare earths. The resultant pregnant leach solution, after acid recovery, will be a suitable feedstock for purification and separation of the valuable rare earths. The PEA will compare a conventional route to produce a Cerium-depleted mixed rare earths carbonate versus an alternative flow sheet that bypasses the carbonate stage and delivers three higher value products, comprising NdPr oxide, Tb oxide and Dy oxide[1]. The results will then guide the direction for development of a pre-feasibility study.
The scope of the PEA has been enlarged from the original plan to now include a downstream processing step, as an alternative to the original flowsheet which will produce a mixed rare earth carbonate. This is possible at Phalaborwa owing to the fact that the rare earths contained in the phosphogypsum are in a "cracked" chemical form. Further downstream processing to separate and purify individual oxides is anticipated to deliver the following benefits compared to a traditional flowsheet:
· The enhanced flowsheet is expected to be capable of delivering a higher value product, delivering the full value of the separated rare earth metal oxides. By comparison, Rainbow's Gakara project produces a high-grade mineral concentrate, which has been sold to China for further downstream beneficiation/processing, realising approximately 30% of the contained rare earths metal oxide value. The traditional flowsheet at Phalaborwa would produce a mixed rare earth carbonate, realising approximately 60% - 65% of the contained metal oxide value, compared to 100% of the metal oxide value we would achieve by going further downstream to produce separated individual oxides as a per the enlarged PEA scope of work.
Go and read it.
Why not read the RNS from a couple of years ago.
53% from memory
>>What is the NdPr content in your concentrate?
You quoted the price for Chinese standard carbonate.
You should have know the relevant constituent's of that material before quoting its price.
Opex is approximately half of the Oxide. i.e. $34/2 =$17k per ton cost of production
45% carbonate contains 20% NdPr, so 9% NdPr per ton, value of metal= $44.44k per ton income
Even if $34 value is used, its still very profitable. And the secondary gypsum is worth ~ $3 per kg. off the opex.
>>what are these elements
Cerium, its worthless REE. many plants remove it from the Carbonate as did RBW in their original MREC pilot plant
Delay was to add a step to produce cerium-depleted mixed Carbonate.
Reducex energy costs and more efficient reagent recovery.
Few more weeks to gull results.
