Revolutionizing Battery Materials: TMC’s Breakthrough in Deep-Sea Nickel Sulfate Production

In a groundbreaking achievement, The Metals Company (TMC), in collaboration with SGS, has successfully produced the world’s first nickel sulfate from deep-sea polymetallic nodules.

This innovative process directly converts high-grade nickel matte into nickel sulfate, bypassing the production of nickel metal, and simultaneously generates valuable fertilizer products. The implications are far-reaching, especially for the burgeoning battery market.

TMC holds exploration rights to the world’s two largest-ranked undeveloped nickel deposits. These untapped resources offer a compelling alternative to the environmentally impactful nickel laterites sourced from rainforests. By harnessing deep-sea nodules, TMC aims to reduce the ecological footprint associated with traditional nickel extraction, benefiting both ecosystems and local communities.

Dr. Jeffrey Donald, TMC’s Head of Onshore Development, emphasizes the significance of this achievement: “The production of the world’s first nickel sulfate from deep-seafloor nodules is an important milestone. Our custom flowsheet configuration demonstrates that these remarkable rocks can be processed into final products suitable for use in batteries.

“Collaborating closely with SGS and industry leaders, we’ve refined nodules into high-value materials. As we move toward commercial scale, leveraging existing processing facilities through strategic partnerships, we anticipate a capital-light approach. This achievement not only marks a major milestone for TMC but also signals a transformative era for the entire deep-seafloor minerals industry.”
