ReElement–Principal rare earths production partnership targets a unified US supply chain

ReElement Technologies

ReElement–Principal rare earths production partnership aims to integrate midstream steps in one site. The partners plan separation, fluoride production, and metallization in a single US facility. This ReElement–Principal rare earths production partnership targets lower costs, less waste, and faster scale-up. Therefore, it could tighten domestic loops from feedstock to metal.

One facility, three process steps

The partners seek a unified flow from separation to metal. ReElement will supply separated rare earth products from mined and recycled sources. Meanwhile, Principal will convert feed into rare earth fluorides and metal. As a result, the ReElement–Principal rare earths production partnership could cut logistics and by-product losses. A single site should also improve traceability and quality control.

Siting options and strategic impact

The companies have not selected a final site. However, they are evaluating Marion, Indiana, and Camden, South Carolina. Other locations remain under review for utilities and permitting. As a result, the project could anchor a regional magnet materials hub. The ReElement–Principal rare earths production partnership would strengthen US midstream capacity. It also links recycling with primary supply, improving security and resilience.

The Metalnomist Commentary

If executed, this model reduces handoffs that slow qualification and raise costs. The integrated midstream could become a template for allied projects that pair recycling with new ore, accelerating domestic magnet metal availability.
