American Resources Corp expands research with Purdue University to recycle critical rare-earth elements

American Resources Corporation, a supplier of raw materials to the infrastructure marketplace, headquartered in Fishers, Indiana, USA, has announced an expansion of its existing sponsored research programme with Purdue University, West Lafayette, Indiana. The agreement will focus on advancing the purification of critical and rare-earth elements (REEs).

The partnership builds on a previous agreement to advance a Purdue-developed technology to refine rare-earth elements purification technology to recycle permanent magnets and lithium-ion batteries pulled from sources such as hard disk drives, electric vehicles and wind turbines. The technology was developed in the laboratory of Linda Wang, Purdue’s Maxine Spencer Nichols Professor of Chemical Engineering.

Given the early success of its agreement, American Resources entered into the expanded agreement with the Purdue Research Foundation Office of Technology Commercialization to further refine the ligand assisted displacement (LAD) chromatography process and technology to include the recycling, reprocessing and purification of critical rare-earth elements from lithium-ion batteries, coal waste and byproducts.

The new agreement builds on the acquisition of certain licenses associated with the Purdue-developed technology to separate and purify rare-earth elements using LAD chromatography, technology specific to the recycling of permanent magnets for rare-earth elements.

“Purdue has been a fantastic, innovative and commercially driven partner to work with,” stated Mark Jensen, American Resources CEO. “The rare-earth element purification technology that we are commercialising is extremely exciting, and we are both on the same page in terms of getting it to the market as efficiently as possible. Given the early success of our existing research programme, it made sense to expand the programme in short order to include the feedstocks that we are most focused on, such as lithium-ion batteries and coal-based waste and byproducts.”

“Collectively, our process chain of technology and feedstocks enables us to help restore the domestic supply chain of these critical materials in the most sustainable and environmentally-friendly and beneficial ways ever developed,” he continued. “We believe this is where the US needs to drive innovation and compete with China in this market. The team at Purdue is an important part of this, and we look forward to pushing aggressively forward with commercialisation of the technology and showcasing the low cost and environmentally sensitive technology.”

Rare-earth elements include the fifteen elements in the lanthanide series, plus scandium (Sc) and yttrium (Y). They are essential ingredients for magnets, metal alloys, polishing powders, catalysts, ceramics and phosphors, which are important for high technology and clean energy applications. The global REE market is reportedly approximately $4 billion annually and is growing at 8% per year.

American Resources began staffing up to develop a supply chain and aftermarket for certain end-of-life products with several partners to source waste permanent magnets and lithium-ion batteries specific to this portion of its feedstocks and rare-earth elements “Capture – Process – Purify” process chain. These end-of-life products would include electric/hybrid vehicles, e-bikes, wind turbines, NMR machines, MRI machines and certain industrial motors.

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
