Rotary Air Concentration Research & Development

 RAC Technology Development 

R&D Partnerships & Projects

In 2022, Nimble Resources made significant strides forward in RAC pre-concentration commercialization. Upon joining the “Think & Act Differently” cohort (TAD powered by BHP), Nimble emerged victorious in the “in-mine pre-concentration” challenge . Guided by technical oversight fOrica Digital Solutions and the TAD cohort, Nimbles’ RAC technology was meticulously assesed and evaluated across various parameters and scenarios. This collaboration has yielded a dependable data set, essential for further evaluation and commercialization across the array of pre-concentration opportunities.

DIXIE R&D Trial Mining Event

Nimbles prototype test plant is Situated near Kalgoorlie at our Dixie Operations Mine-Site. Commercial scale testing is now complete, with thousands of machine and assessment hours and 150,000 tons of ore processed, clear pathways to commercialization and RAC scalability are now clear.

RRE (Rear Earth Elements R&D

Focus on Monazite hosted TREO. In Q3 of 2024 Nimble resources will undertake a bulk trial mining event to evaluate RAC technology for pre-concentration of placer TREO deposits.

Next Steps

Continuation of test work to encompass a range of mineral ore types with different specific gravities, particle densities and air concentration characteristics. Within the TAD cohort, Nimble has ongoing R&D programs running throughout 2024 and beyond.
