Brazilian Rare Earths Limited (ASX: BRE / OTCQX: BRELY) conducted a successful metallurgical program at CDTN, achieving very high extraction rates of 97% for Total Rare Earth Oxides, 97% for Neodymium + Praseodymium, and more. The low-temperature, acid-cure process showed potential for lower opex and capex costs with a total ‘mineral-to-product’ recovery of ~91% TREO.

The results of the program support the potential for leading total system yields, with a total system product recovery of 92% for NdPr, up to 82% for heavy rare earths DyTb and Y, and 89% for uranium. This acid-cure process eliminates the need for energy-intensive thermal cracking, allowing for scalable deployment at the processing hub in Camaçari.

BRE Managing Director and CEO, Bernardo da Veiga, highlighted the industry-leading recoveries for rare earth and uranium products achieved through the low-temperature, acid-cure process. The results will unlock value from high-grade mineralization and enable the integration of multiple high-grade feedstocks into a flexible production platform.

The program also identified opportunities for further optimization, such as shortening wash durations and optimizing process acids, while maintaining high extraction performance. The results are promising for the company’s plans to apply the proven flowsheet to their broader resource base, enhancing efficiency and cost performance in rare earth processing.
