MONTREAL, Oct. 30, 2023 /CNW/ - Central America Nickel Inc. (the 'Company' or 'CAN') is pleased to announce that it has filed a PCT application (PCT/CA2023/051387) and a patent application in the Democratic Republic of the Congo titled 'Process for Extraction of Rare Earth Elements' for the extraction of rare earth elements using the Company's Ultrasound Assisted Extraction (UAEx) technology.
The patent-filed process is a combination of a process for the extraction and recovery of rare earth elements, and the selective extraction and separation of radioactive components (uranium and thorium) from rare earth components with the use of CAN's ultrasound technology, the Ultrasound Assisted Extraction (UAEx), as a process intensification method. The separation of radioactivity from rare earth concentrates is crucial for the ability to export and transport material internationally, as well as for further processing into refined end-products intended for the green industries.
The UAEx is an environmentally-friendly alternative to conventional processing methods as it increases mineral recovery rates while reducing processing time; the process enables minerals to separate from ore and into solution more efficiently and at a lower cost than traditional processing methods, with significantly less environmental impact including substantially minimized CO2 emissions, waste and energy requirements.
Over 84% recovery of rare earths in solution was achieved using the UAEx, with recoveries of 92% of neodymium, and a 100% recovery of praseodymium, gadolinium, and iridium.
Given the complexity of extracting and refining rare earths elements, the use of CAN's proprietary technology and processes could represent a major extractive industry advancement.
Rare earth elements are profoundly valuable and critical in the manufacturing of a variety of modern devices including high-strength magnets, batteries, displays, electronics, lighting and high-performance metal alloys. Rare earths are listed on the critical mineral lists outlined by the governments of Canada and the United States.
