The investment will enable the company to accelerate commercial deployment of its Molten Oxide Electrolysis platform, enabling production of strategic metals from a diverse range of low-grade feedstocks.
BOSTON—Boston Metal, a technology company aiming to redefine global metals production, reported in May that it raised $75 million to accelerate the deployment of its Molten Oxide Electrolysis (MOE) platform and scale production of critical metals in the U.S. and globally.
According to a company release, 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. The selectivity of MOE unlocks resources from low-grade materials, offering a new pathway to strengthen supply chains for materials essential to electrification, advanced manufacturing, AI, and defense.

Tata Steel Limited joined the round, along with existing investors, signaling strong industrial and investor demand for novel approaches to critical metals production.
“This financing marks a pivotal step for Boston Metal,” said Rick Cutright, technology director at Climate Investment, in the release. “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 can expand supply from materials that conventional processes leave behind.”
Demand for critical metals is surging across electrification, advanced electronics, infrastructure development, and defense, while supply remains constrained by geopolitics and environmentally intensive extraction. Boston Metal’s MOE platform is said to directly address this market demand.
One way it does so is by enabling efficient recovery of high-value metals from a wide range of metallurgical and industrial waste streams. Another way is by boosting yields and lowering capital costs to create new commercialization opportunities for low-grade mineral projects.
“Critical metals are the new strategic commodities,” said Tadeu Carneiro, CEO of Boston Metal, in a statement. “MOE is creating a scalable and cost-effective pathway to recover critical, high-value metals, support industrial onshoring, and strengthen the secure supply of critical materials needed for advanced technologies, manufacturing, and AI.”
“The world doesn’t just need more metals, it needs smarter, more adaptable ways to produce them,” added Mark Cupta, managing director at Prelude Ventures, in the release. “MOE stands out for its flexibility as a true platform technology, capable of operating across multiple metal systems with a high degree of selectivity. The Boston Metal team has developed a differentiated technology and is now utilizing that technology to unlock a new generation of critical metals assets.”
The new capital brings Boston Metal’s total funding raised to more than $500 million, the company said.
