Iluka Resources has awarded JordProxa Pty Ltd (Perth, Australia) the contract to supply a custom-engineered CO₂ capture plant for its flagship Eneabba rare-earths refinery in Western Australia — a first-of-its-kind facility in Australia and among only a few rare earths refineries outside China.
This award further strengthens the collaboration between Iluka and JordProxa, building on JordProxa’s earlier contract for ten modular evaporation plants at Eneabba.

The CO₂ capture plant is designed to recover carbon dioxide from boiler off-gas using an aqua ammonia solution, producing a controlled ammonium carbonate/bicarbonate mixture at the desired pH. This process is critical not only for meeting emission standards for ammonia but also for achieving precise CO₂ recovery, which plays a key role in downstream process chemistry.
JordProxa’s solution includes three gas processing columns: one for gas conditioning and primary cooling/polishing, and two for CO₂ absorption and final gas polishing. The system has been carefully designed to minimize energy usage and reduce operating costs without compromising on recovery efficiency or environmental performance.
While the large columns are supplied loose for on-site assembly, pumps, heat exchangers, and ancillary systems are delivered in modular skids — allowing for simplified installation, reduced on-site risks, and improved quality through controlled off-site fabrication.
