Critical metals processing innovator Boston Metal raises another $75m for scaling MOE tech
A technology company with ambitions to redefine global metals production, Boston Metal, has raised $75-million to accelerate deployment of its Moltex Oxide Electrolysis (MOE) platform and scale production of critical metals in the US and globally.
The new capital brings the company’s total funding raised to more than $500-million.
Designed to operate across a wide range of metal oxides, MOE enables production from diverse feedstocks, creating a scalable and cost-effective pathway to unlock new economic opportunities in metal refining, support industrial onshoring and strengthen the supply of critical metals.
In particular, the technology’s selectivity unlocks resources from low-grade materials, offering a new pathway to strengthen supply chains for materials essential to electrification, advanced manufacturing, AI, and defence.
The funding will enable Boston Metal to expand its critical metals business through additional commercial-scale deployments for metals such as niobium, tantalum, vanadium and nickel.
Tata Steel is among Boston Metal’s latest contributors, along with existing investors, which the company says signals strong industrial and investor demand for novel approaches to critical metals production.
“This financing marks a pivotal step for Boston Metal. The company has built a new metallurgical platform and demonstrated its ability to produce high-quality metals from complex feedstocks; now the focus is commercial production.
"Critical metals are the right first market because the need is immediate, the economics are attractive and MOE technology can expand supply from materials that conventional processes leave behind,” says investment firm Climate Investment technology director Rick Cutright.
Demand for critical metals is surging across electrification, advanced electronics, infrastructure development and defence, while supply remains constrained by geopolitics and environmentally intensive extraction.
Boston Metal says its technology platform directly addresses this market demand by enabling efficient recovery of high-value metals from a wide range of metallurgical and industrial waste streams; and boosting yields and lowering capital costs to create new commercialisation opportunities for low-grade mineral projects.
Boston Metal CEO Tadeu Carneiro believes critical metals are the new strategic commodities and that the world does not just need more metals but smarter and more adaptable ways to produce them.
