SelectREE Reports Repeatable Electrochemical Responses Across Four Elements

Key Terms

solvent extraction technical

Solvent extraction is a chemical separation method that uses a liquid solvent to pull a specific substance out of a mixture, similar to using oil to lift grease from water. Investors care because it affects how efficiently and cheaply a company can isolate valuable materials—like metals, oils, or pharmaceutical compounds—which influences production costs, output quality, environmental permits and the potential for regulatory or disposal liabilities.

electrochemical process technical

An electrochemical process uses electricity to drive or control a chemical change, such as charging a battery, plating metal, detecting substances with a sensor, or breaking down pollutants. Investors care because these processes determine how well products work, how much they cost to make, and how they meet safety or environmental rules; think of it like using an electric pump to rearrange parts inside a machine—efficiency and reliability affect profit and market edge.

leaching technical

Leaching is the process by which chemicals or contaminants are washed or seep out of a material—like heavy metals leaching from old pipes or additives bleeding from plastic—into surrounding water, soil, or products. Investors should care because leaching can trigger regulatory fines, costly cleanup, product recalls or liability claims and damage a company’s reputation, much like a slow leak can silently flood a house and force expensive repairs.

rare earth separation technical

Rare earth separation is the industrial process of extracting and sorting the individual rare earth elements from mined rock or mixed chemical compounds so each metal can be used in electronics, magnets and other technologies. Investors care because the step is often the most complex, costly and environmentally sensitive part of the supply chain — like untangling a box of mixed screws into labeled bins — and it affects availability, price and regulatory risk for companies using these metals.

Laboratory results mark an initial technical milestone toward replacing complex solvent extraction separation with a modular electrochemical process

PETAH TIKVA, Israel--(BUSINESS WIRE)-- SelectREE, a developer of electrochemical separation technology for rare earth and critical metals, is pleased to announce an important technical breakthrough: clear and repeatable element-specific electrochemical responses have been recorded across its electrode systems. The laboratory work covered four elements over dozens of runs conducted during several weeks, providing the first technical indication that the company’s approach can consistently distinguish between individual elements.

The results represent an important step in SelectREE’s proprietary effort to replace the conventional solvent extraction stage of rare earth separation with an electrochemical process designed to be smaller, more modular and deployable closer to the source material.

Addressing the Separation Bottleneck

Rare earth elements are typically found together and have very similar chemical properties, making separation into individual, high-purity elements one of the most technically challenging stages of the supply chain. China accounts for approximately 91% of global rare earth separation and refining, according to the International Energy Agency, with Malaysia a distant second.

The conventional method, solvent extraction, generally requires large chemical plants with hundreds of stages, significant volumes of acids and solvents, and complex waste management systems. These facilities can be capital intensive, time consuming to build and difficult to permit.

SelectREE’s proprietary platform is designed to change the separation stage, not the upstream leaching process. Ore or recycled material would still be leached using a solution selected for the relevant feedstock. That solution would then be processed through SelectREE’s electrode-based system rather than through hundreds of solvent extraction stages.

First Technical Milestone

SelectREE’s latest laboratory results demonstrate distinct and repeatable electrochemical signatures for the elements tested. Consistently differentiating between elements is a foundational requirement for any selective separation process and provides the basis for the company’s next phase of development using real-world feed materials.

Discussing these results, Dr. David Malka, Chief Executive Officer of SelectREE commented, “When the curves stopped overlapping, we saw the first clear indication that electrochemistry could offer a new pathway beyond the century-old solvent extraction process. Rare earth elements are essential inputs for permanent magnets used in electric vehicles, wind turbines, hard drives, drones and guided defense systems. The ability to separate and refine these materials is therefore central to establishing secure, independent supply chains.”

Path Toward Commercial Deployment

SelectREE’s development plan consists of three principal stages: demonstrating that its electrodes can distinguish between elements; validating the process using real feed materials; and deploying a pilot unit at a customer site. The company’s long-term objective is to enable mine operators, manufacturers and recyclers to separate metals closer to the point of production or recovery, without waiting for a conventional centralized separation plant to be built.

The platform is being developed for primary ore, end-of-life magnets, manufacturing swarf and other material streams. SelectREE also intends to evaluate applications beyond rare earths as a broader electrochemical tool for mineral separation and refining.

SelectREE is backed by Cove Capital LLC, which invested in the company in April 2026 through one of its Portfolio companies. Cove Capital is led by Pini Althaus, a mining executive with more than two decades of experience across critical minerals.

“Separation remains one of the most consequential bottlenecks in the critical minerals supply chain. We backed SelectREE because its technology has the potential to make separation more modular and accessible at mine sites, manufacturing facilities and recycling operations, helping countries build supply chains that do not depend on a single processing center,” said Pini Althaus, Founder and CEO of Cove Capital LLC.

About SelectREE

SelectREE develops electrochemical separation technology for rare earth and critical metals, seeking to replace the solvent-extraction separation stage with an electrochemical process. Based in Petah Tikva, Israel, the company is developing its platform for primary ore, end-of-life magnets and manufacturing swarf. The approach is also being evaluated as a broader tool for separation and refining across the mining industry.
