TMC, in collaboration with SGS, has achieved a groundbreaking milestone in the processing of deep-seafloor polymetallic nodules. The world’s first cobalt sulfate has been successfully produced, showcasing the potential of TMC’s resource for the battery and energy transition markets.
Using TMC’s efficient flowsheet design, the testing program resulted in the direct production of high-purity cobalt sulfate from high-grade nickel-copper-cobalt matte. Notably, this process eliminates the need for producing cobalt metal and instead generates valuable fertilizer products, minimizing solid waste and tailings.
Dr. Jeffrey Donald, TMC’s Head of Onshore Development, emphasized the significance of this achievement in expanding the possibilities of seafloor polymetallic nodules as a valuable resource. Following the successful production of nickel sulfate last month, the production of cobalt sulfate further underscores TMC’s commitment to sustainable and responsible metal sourcing.
Carlos Cordoba, Vice President of Natural Resources at SGS North America, praised the collaboration with TMC and highlighted the innovative approach driving progress in the mining industry.
This milestone aligns with TMC’s mission to provide essential metals for the global energy transition while minimizing environmental impacts. With the increasing demand for critical battery metals like nickel and cobalt, the successful extraction of cobalt sulfate from seafloor nodules marks a significant step towards securing a stable and responsible supply chain for the future.
