Modernizing Metals Refining for a New Economy

The Oyster uses electro-extraction, combining water and electricity to recover critical metals. Electro-extraction is a safer and less energy-intensive alternative to traditional, energy-intensive refining methods. Our novel, low-emission technology can be applied in mining, from extracting metal trapped within low-grade minerals and mining waste streams, to recycling, by salvaging material from end-of-life scrap. We’re closing the mining production loop and making metals infinitely reusable.

We partner with clients to understand their refining needs, deploying our modular and scalable Oyster extraction units on site, saving clients time, capital, and the carbon emissions associated with transporting material to traditional refining and recycling facilities.

We’re Building a Sustainable Metals Industry

We’re passionate about using technology to construct a sustainable world; we believe the metals refining industry can lead this change. Backed by 150 years of combined experience, our team is modernizing metals refining to be cleaner, safer, and circular.

Bringing Process Metals Home

We are already leading the way to an electrified economy with the opening of our Fairfield, Ohio Electro-Extraction refining facility using Oyster technology. This is the first U.S. facility to refine material into premium nickel cobalt mixed hydroxide precipitate (MHP), a key battery material. The plant can cut greenhouse gas emissions by more than 92% compared to traditional energy-intensive smelting operations, aligning with the Inflation Reduction Act requirements and national security concerns.

Our clients operate in many industries including:

  • Battery Manufacturers
  • Original Equipment Manufacturers
  • Electronics Manufacturers
  • Scrap Recyclers
  • Miners
