Duranium
Reshoring critical metal production
Duranium is active in the industrials space based in San Francisco, CA, USA.
Profile
China and Russia control the world’s critical minerals. We can produce Titanium, Magnesium, Aluminum, Zirconium & Hafnium in the U.S. more profitably than any existing process, and carbon neutrally via co-production.
Carbochlorination is the primary process for producing critical metals like titanium, hafnium, and zirconium, and was once the standard for magnesium. The problem: conventional carbochlorination relies on purchasing carbon feedstocks, wastes valuable byproducts, and is highly CO₂-intensive.
Duranium changes this with a novel reactor that recycles CO₂ emissions back into feedstock (CO) while generating a valuable co-product (bleaching agents). This closed loop slashes emissions and delivers Chinese-level metal pricing without subsidies — unlocking the full potential of carbochlorination for U.S. critical mineral production.
Duranium is positioned in industrials, a segment that rewards a clear, focused offering.
The business is associated with San Francisco, CA, USA.
The company is listed at the Summer 2025 stage of development.
The company reports a headcount in the 10 range.
Directory analysis
Duranium produces critical metals—titanium, magnesium, aluminum, zirconium, and hafnium—in the United States using a novel carbochlorination reactor that recycles CO₂ into feedstock and generates valuable co‑products, aiming for carbon‑neutral, cost‑competitive production. The company claims its closed‑loop process can deliver U.S. prices comparable to Chinese levels without subsidies. It seeks to reshape the critical minerals supply chain by reshoring production.
Positioning: Duranium targets a niche, strategically important market by offering a potentially lower‑emission, cost‑effective alternative to traditional critical metal production. While its technology could address supply chain vulnerabilities, the company’s commercial success and scalability remain to be demonstrated.
Note: Duranium focuses on carbon‑neutral, U.S. production of critical metals.
