P Rock for Peace: Sustainability on Trial• Mission: “peaceful, socially beneficial, economically viable, environmentally sustainable exploitation of a natural resource of limited quantity, essential for all life…”
• P Rock for Peace = Food, Feed and Energy – Phosphoric acid (P2O5)
• DAP, MAP, DCP, – Recovered Uranium (U3O8)
• Energy for developing economies• Follow the P life-cycle “Earth to Earth”
![Page 6: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/6.jpg)
Drivers and Constraints• Food security– Access– Prices– Concerns about long-term build up of residues in soils, eg heavy metals, radionuclides
• Energy security– Competition for land (food crops or renewable energy crops)
• G20 – the new economic order• Demographics – the new world aged 25 or younger• Recent failures of the market economy• Extreme price volatility, eg P fertilisers, U, sulphur
![Page 7: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/7.jpg)
Is the management of essential resources such as P and U too
significant to entrust solely to the market?
Or should there be a concerted national and international plan to
manage such resources in a strategic manner to benefit all and to reduce the likelihood of future conflict over access
to critical resources?

Opportunity: U recovery from P2O5This is the third wave
(1. 1960s, 2. 1970s, 3. 2010s?)But at a unique moment in the evolution of the phosphate industry
• Move from US/EU to BRICS and emerging economies• Different perspective on management of key
resources, such as P and U• Relative lack of knowledge and experience• Relative lack of constructive regulatory framework
aimed at economic and social development
![Page 9: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/9.jpg)
P and U as utilities not commodities…managed
under a new social contract for “win/win”?

P2O5 A Potential Major Unconventional Source for Uranium• Phosphate Deposits Contain Uranium
– Nature and value of deposits in phase of extreme transition
• A well-tested additional cycle in P acid production– Range: 0.1-7 Kg/Tonne of P2O5– Typically: 0.3-0.6 Kg U per Tonne P2O5– Price: Volatile, but in 2007, U3O8 Reached $300/KG– Currently $ c.100/Kg on Spot Market and $150/Kg for some Long Term Contract

Experience to Date• Quantity: c. 20 million Kg of U3O8 has been Recovered from Phosphoric Acid• Lifecycle: Many Plants Operated for 10 Years+• HSE: No Significant Issues to Date
• Elimination of TLD Badge after Urine Analysis• Minimal Health Physics Requirements - Refinery Building Only
• Markets: CF, Mosaic and Morocco Have Announced that They Are Considering Building Uranium Recovery Plants

Life-cycle Cost Analysis:Opportunities to Reduce Cost of “Next Generation” Plant
• Each Previous Plant had Strong and Weak Points
• Applying Lessons Learned will Reduce both Capital and Operating Costs– Solvent losses varied by a factor of 3 +– Pretreatment Costs Varied by a factor of 3 +– Total of Solvent Loss and Pretreatment varied by a factor of 3 +
.

Opportunities to Reduce Cost of “Next Generation” Plant
• For Example– Average Solvent Concentrations in the Raffinate Ranged From 5 ppm to 100 ppm
– Strip Coefficients Ranged from 15 to 150– Solvent Loss Due to Settler Cleanings Ranged from <.02 to >0.1 Kg/Tonne P2O5Processed
– Some Plants had Negative Impact on Fertilizer Production, Some Had Positive Impact .

Estimated Capital Costs: New Generation Plants
• Capital Costs (inflation adjusted) – Estimated lower than for previous generation Plants
– Highly Dependent on Flow Sheet Adopted• Cost Driver – Equipment Selection: In all Previous Generation Plants– Significant unnecessary components, resultant on poor design
– Replaced/ replaceable with less expensive items
![Page 23: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/23.jpg)
Estimated Operating Costs: New Generation Plants
• Projected - less than $40/Kg• Cost Contingencies:
– Uranium Content of Rock (In USA, 0.45 Kg/Tonne projected 2010-2020; previous estimated 0.35-0.4 Kg/Tonne)
– Consumables• Solvent (trend higher)• Electricity (trend higher)
– Labour (trend higher, but with potential offset with automation)– Regulation (negative externality)

Break-even Point
As a Rough Rule of Thumb, at a Uranium Price of $ 100 /Kg, any Plant That Can Produce at least 200,000 Kg U3O8/yr Should Give a 10 Year Pay Back

Uranium Recovery Plant: Build Timeline1. Flow Sheet: 3-6 months2. Cost Estimate: 3-6 months3. Permitting: 6-18 months, in parallel with 1 and 2
– Very little waste generated, but agreements needed on storage/ disposal
4. Detailed Design: 6-12 months5. Construction: 12 months6. Start-up: 1-3 months
• Total time: 25-45 months• Total Capital: $70,000,000 – $200,000,000

Win/ Win: Recovering Uranium -Futureproofing
• Slow or Eliminate Uranium Build-up in the Upper Soil Horizon…
• So Help Prevent Eventual Long-term Catastrophic Consequences for Food Security
• Recover, Use/ Stockpile an Essential / Strategic Energy Resource
Multi-dimensional issue requiring multi-disciplinary responses – we must talk to, and learn from, each other…
![Page 29: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/29.jpg)
Morocco (1) - Context• Critical point in the evolution of the national economy
• P is the key industry (40% of all foreign earnings, 5%+ of GDP)
• To date only medical and related uses of nuclear materials; small reactor at CNESTEN
• JV with Aveva on U recovery• Predictable surge in national and regional demand for energy
• Win/win?
![Page 30: Uranium and Phosphorus - Atoms for Peace and · PDF fileUranium and Phosphorus: ... • JV with Aveva on U recovery • Predictable surge in national and regional demand for energy](https://reader034.fdocuments.us/reader034/viewer/2022052419/5a7079e07f8b9ab6538bf9d1/html5/thumbnails/30.jpg)
Morocco (2) – Possible Solution• Wish to regulate is a “constructive” way, ie evidence-based, but contributing to economic and social development
• Proximity to Spain and France• Human capital – COE (CNESTEN) and Industry Leader (OCP) well able to do this technically and financially
• Wish to align with international norms and laws, but also to foster national interest
• OCP has a conscious “Leadership” policy: this would be a very good issue to lead on

IAEA Group: Ideas for Future Work Plan• Create organisational vehicle for cross-cutting
cooperation and enable win/win outcome• Evaluate alternative extraction technologies on “Level
Playing Field”(Based on a Specific Plant or Group of Plants)• Consider / Mitigate all Impacts,
– Policy-driven delays and regulatory constraints– Loss of Institutional Memory (Average Age of “Experts” is >70
• Publish on-going Triple Bottom Line Analysis based on Full Life-cycle Cost Analysis
• Train competent future operatives based on past and current experience (preserve organisational memory)

What About Phosphoric Acid Plants that Use the Hemi Process?• Even if the Uranium Content is about Half• Since the Acid is ~40% P2O5, Uranium Content in g/l is Similar to Central Florida
• Octyl Phenol Phosphoric Acid Solvent has Been Demonstrated to Work Effectively in Lab
• Operating and Capital Costs will be about the Same per Kg as Central Florida (But Less Kg Produced)
• Piloting is Probably Required .optional slide
