Aclara receives second patent for extraction process

ACLARA RECEIVES SECOND PATENT FOR ITS INNOVATIVE PROCESS TO EXTRACT SUSTAINABLE HEAVY RARE EARTHS

Aclara Resources Inc.'s second patent for its groundbreaking process to extract heavy rare earths in an environmentally friendly way has been received. The patent has been granted in Chile and is valid for 20 years. It centres around the innovative circular mineral harvesting (CMH) process created by Aclara, a groundbreaking technique for processing ionic clays housing rare earths. CMH establishes a fully enclosed flowsheet, setting a new standard for sustainable rare earth extraction.

Circular mineral harvesting -- environmental attributes:

  • No crushing or milling required;
  • 95 per cent of water used is recirculated;
  • 99 per cent of the reagent (a common fertilizer) recycled back into the process;
  • No liquid residues and no tailings dam needed;
  • No radioactivity.

This patent grants Aclara the right to exclude others from using or selling products made by its unique process. Special emphasis has been placed on two parts of the process: the water and the reagent recirculation components of the flowsheet, recycled with 95-per-cent and 99-per-cent efficiency, respectively. Aclara stands apart from other mining operations in its sector by not having a tailings dam, a distinction achieved through the absence of liquid residues. At the end of the extraction process, Aclara's environmentally friendly spent clays are suitable for revegetation with native species, reinforcing the ecofriendly nature of the company's extraction process.

Barry Murphy, chief operating officer, commented:

"This is a great milestone for Aclara, putting the company on track to become the cleanest source of heavy rare earths in the world. This patent underscores our commitment to innovation in the rare earths industry. Our team's ongoing dedication to advancing environmental standards goes hand in hand with our continuous efforts to optimize both capex and opex, solidifying our leadership in responsible resource extraction."

Aclara's process has been successfully tested at its pilot plant in Concepcion, Chile, with ionic clays from its Chilean project last year, and where the ionic clays from its Brazilian project are being processed. Aclara is expecting to produce around 10 kilograms of a high-purity heavy rare earths concentrate for commercial uses, and it should have the results of this piloting campaign in the next month.
