Terrafame

Terrafame is a Finnish multi-metal company that operates one of the world's largest nickel and cobalt sulfate production lines for electric vehicle batteries. Located in Sotkamo, Finland, the company utilizes a unique bioheap leaching process that leverages microorganisms to extract metals from low-grade ore with significantly lower carbon emissions than traditional methods. Terrafame transitioned from a pure mining operation to an integrated battery chemicals producer with the 2021 launch of its state-of-the-art crystallization plant. The company is a strategic asset in the European battery ecosystem, providing a domestic, traceable, and sustainable source of critical raw materials. Its primary products include high-purity nickel sulfate, cobalt sulfate, and zinc sulfide.
