Radify Metals is developing a plasma-based refining approach for rare earth elements and other metals. The startup says the technology could make the step that converts metal oxides into pure metals more efficient and less polluting than the heat- or water-based methods commonly used today. In an exclusive look shared with TechCrunch, the startup frames its technology as addressing a specific supply-chain bottleneck in rare earth processing, where China currently holds significant market position.
The refining bottleneck in rare earth supply chains
Rare earth elements represent a small portion of the global metals market but carry outsized geopolitical weight. China holds considerable leverage in this sector, which has become a factor in trade disputes. The U.S. and other countries have taken steps to reduce this dependence, including opening new mines and supporting manufacturers that produce magnets and motors. However, this shift has been slow—China built its position over several decades.
Radify CEO and co-founder Zach Detweiler identified a specific supply-chain gap. “In order to be able to support an entire industrial base, you’ve got to have that whole supply chain node-matched in terms of capacity,” he told TechCrunch. He pointed to the conversion of metal oxides into pure metals as the overlooked link: “That’s this missing middle we’ve identified.”
Most metal refining uses either heat or water—often combined with other elements—to strip oxygen from metal oxides, producing pure metal that can be incorporated into alloys for stronger magnets or more efficient electronics. Both processes are effective but highly polluting. This creates a constraint for scaling supply chains: even if new mines and magnet manufacturers emerge, the refining step must operate at industrial scale while meeting environmental and operational requirements.
Plasma refining as a lower-pollution alternative
Radify’s core technical approach centers on plasma refining. Plasma is essentially a superheated mixture of super-energetic particles that can strip oxygen from metal oxides, leaving pure metal. The process’s only reported waste is water vapor.
Plasma refining is not new—the concept has been known for some time but was considered too expensive for commercial production. The cost and scalability challenge is therefore not just whether plasma can perform the chemical work, but whether the process can be built and operated efficiently enough to run continuously and handle real-world materials.
Radify claims it has addressed the plasma problem through more efficient power electronics and engineering designed to handle metallic powders. These improvements directly target two practical barriers: energy efficiency (power consumption per unit of output) and materials handling (managing metallic powders without degrading performance or creating operational bottlenecks). The technology is presented as a system-level design intended to make plasma refining viable for industrial throughput.
Current focus and funding
Radify said its reactor can transform a wide range of metal oxides. The startup’s near-term focus is narrower: dysprosium and samarium, two rare earths used as key ingredients in magnets and electronics. This focus aligns with immediate demand from magnet and electronics manufacturers.
Radify has raised just under $3 million from investors including Overture, Founders Inc., Mana Ventures, and Acequia Capital. The funding level and investor roster suggest early-stage development and validation work, though specific milestones supported by the funding were not disclosed.
Implications for rare earth supply chains
Radify’s approach sits at the intersection of materials processing and environmental constraints. The contrast between the high pollution of conventional heat or water refining and plasma refining’s reported water vapor-only waste could influence how future rare earth supply chains are structured. If the system-level efficiency and powder-handling engineering perform as described, this could reduce dependence on geographically concentrated refining nodes in existing supply networks.
Observers may watch for engineering details that determine cost-competitiveness: the performance of the power electronics, the robustness of the powder-handling system, and whether the reactor can scale beyond dysprosium and samarium. The source does not provide performance metrics, so further reporting or published technical results would be needed to assess feasibility.
