In a groundbreaking move this past April, Niocorp Developments announced plans to investigate the feasibility of recycling permanent rare earth magnets. This initiative is set to become a significant component of NioCorp's proposed Elk Creek Critical Minerals Project (the "Elk Creek Project") in southeast Nebraska. This exploration could reshape the landscape of rare earth element utilization and sustainability.

Pioneering Rare Earth Magnet Recycling

NioCorp's focus is on the recycling of post-consumer neodymium-iron-boron (NdFeB) permanent rare earth magnets. The goal is to transform these used magnets back into separated rare earth oxides, which can then be used to manufacture new NdFeB magnets. This process is not only innovative but also crucial for promoting circular economy principles within the industry.

 

The research will initially concentrate on bench-scale testing to assess technical and commercial viability. Depending on the outcomes, the project might advance to demonstration-scale testing. Importantly, this investigation will be conducted separately from the ongoing efforts to update the Elk Creek Project Feasibility Study.

The R&D Program: A Step-by-Step Approach

Once initiated, the R&D program will aim to develop efficient processes for demagnetizing, preparing, and grinding down used magnets into feedstock. This feedstock will then be processed through NioCorp's planned Elk Creek Project chemical processes to yield separated rare earth products.

Overcoming Recycling Challenges

Recycling rare earth permanent magnets poses unique challenges due to their varied shapes, sizes, and formulations. These magnets are inherently brittle and are often coated with other metals to prevent corrosion, complicating the recycling process. However, NioCorp believes its Elk Creek process can handle these complexities.

The Potential Impact

If the feasibility of NdFeB magnet recycling is successfully demonstrated and NioCorp secures sufficient financing for the Elk Creek Project facility, the company could significantly increase its production of neodymium-praseodymium oxide, dysprosium oxide, and terbium oxide. This increase would go beyond what is contained in the Elk Creek ore body, marking a substantial advancement in rare earth element production.
