Positive results from real-world trials.

Development of the PhosEnergy Process has progressed past pilot plant scale at a significant USA based phosphoric acid facility with positive results.

Operation of the first PhosEnergy pilot plant has proven that the robust process capable of achieving high levels of uranium recovery at the lower end of the cost curve.

A major phosphoric acid facility in the USA has achieved positive results.

Subsequently a Demonstration Plant has been built within two 40 ft shipping containers. The containers have proven to be unpacked and ready for operation within three days once delivered to site (see photos here).  The plant meets Australian and US safety standards, with incorporation of automated emergency controls (via SCADA control system), emergency wash stations and electrical earthing. A self-contained off gas handling system, and secondary containment system ensures environmental compliance.

The state-of-the-art plant is fully process controlled and data can be managed via the internet anywhere in the world, facilitating the gathering of the key data in order to test the efficacy of the PhosEnergy Process under industrial conditions.

The Demonstration Plant, pictured below, was commissioned in May 2012 in the USA and operated during June to August 2012 on phosphate streams from two different fertiliser facilities with exceptional results, including:

  • Consistently high uranium recovery (greater than 90 per cent) from the phosphate stream during steady-state operation;
  • No deleterious build-up of impurities in the extraction media across multiple cycles;
  • Chemical and reagent consumptions within expected range;
  • Purification and concentration of uranium is achievable without significant uranium losses;
  • The chemistry of the phosphate stream is unaffected except for the removal of uranium;
  • A concentrated product was shipped to a uranium production facility where a saleable product can be produced.

The operation collected information to enable completion of an engineering study including chemical consumption rates, equipment design criteria and energy inputs.

A PhosEnergy Process plant could be in production from 2015. An engineering study is planned to commence at the end of 2012.

Urtek’s strategy is to maintain its technological and development timeline advantages to secure joint development opportunities with one or more phosphoric acid producers in one or more phosphoric acid producing districts to gain a share of uranium off-take revenue as soon as practicable.

Urtek’s internal research has shown both the timing of the PhosEnergy Process development and cost advantage over competitor processes will afford Urtek an advantage in negotiating these equity relationships with future development partners in mutually beneficial ways.

The development of the PhosEnergy Process has advanced to an exciting stage of near term production.
