From Ore Intermediate to ≥99.9% Pure Nickel.
Westwin transforms nickel intermediates into Class 1 metal products using carbonyl refining — a proven, century-old process re-engineered for modern American manufacturing.
A CENTURY-OLD PROCESS, REFINED FOR TODAY.
Carbonyl Overview
Developed in 1890 and commercialized in 1902, the carbonyl process refines metal by vaporizing it under pressure with carbon monoxide — separating pure nickel from impurities at the molecular level. Compared to pyrometallurgy's high-heat smelting or hydrometallurgy's chemical dissolution, carbonyl refining delivers higher purity with lower energy use and less waste.
Competitive Advantages
First-Mover Advantage
America's only Class 1 nickel refinery, reshoring a supply chain the U.S. currently lacks.
