Boston Metal Secures $75 Million to Expand Critical Metals Production
Boston Metal has raised $75 million to enhance its Molten Oxide Electrolysis (MOE) platform for critical metals production. This funding increases total capital to over $500 million, addressing rising demand for critical metals amid supply constraints.

Boston Metal has raised $75 million to scale its production of critical metals, particularly niobium, tantalum, vanadium, and nickel, utilizing its Molten Oxide Electrolysis (MOE) technology. The funding will support commercial operations in Brazil and efforts to recover metals from low-grade materials, boosting yields and reducing costs.
Following cash-flow issues earlier this year, the company aims to commercialize high-value metals, with the Brazilian facility expected to start operations by September 2026. The venture reflects strong demand in electrification and advanced manufacturing, while geopolitical factors continue to impact supply chains. The investment from Tata Steel Limited highlights a growing interest in innovative production methods for critical metals.
