AI agents just figured out how to pull rare metals out of nasty industrial wastewater and old magnets in only a couple of days.

The Takeaway
Developing the chemical processes needed to recover battery and magnet materials usually takes years of human trial and error. By using a network of AI 'agents' to automate the laboratory thinking, researchers successfully turned oil-field waste into a sustainable source of essential materials in a fraction of the time.
From the abstract
We present a multi-agentic workflow for critical materials recovery that deploys a series of AI agents and automated instruments to recover critical materials from produced water and magnet leachates. This approach achieves selective precipitation from real-world feedstocks using simple chemicals, accelerating the development of efficient, adaptable, and scalable separations to a timeline of days, rather than months and years.
