Aclara Produces First REE Concentrate in Brazil with Circular Mining Technology

Aclara Resources

Pilot Plant Targets Heavy Rare Earth Output Through August

Aclara Resources has produced its first rare earth elements (REE) concentrate at a pilot plant in Brazil, marking a key milestone in its integrated mining-to-magnet strategy. In May, the facility processed 14 metric tonnes (t) of ionic clay, yielding concentrates containing dysprosium (Dy) and terbium (Tb). Operations will continue through August, with up to 200t of clays expected to generate approximately 150kg of heavy REE concentrates.

Sustainable Mining and Global Expansion Plans

The Brazilian pilot plant uses Aclara’s proprietary Circular Mineral Harvesting technology, which removes the need for tailings dams and reduces environmental impact. This facility is part of a broader strategy encompassing the Carina Project in Goias, Brazil, and the Penco Module in Chile’s Biobio Region. Aclara also plans to establish a rare earth separation facility in the US. The Carina Project aims to produce 4,736t/yr of total rare earth oxides, including 191t of DyTb, with commercial operations targeted for 2028.

The Metalnomist Commentary

Aclara’s move to pilot REE production in Brazil positions it as a competitive player in the heavy rare earth market. Its low-impact extraction method addresses growing environmental concerns, while its integrated supply chain strategy could help secure critical minerals for the global magnet industry. The success of the Carina Project will be pivotal in determining its long-term market influence.
