A former silver mining region in northern Ontario is set to become the site of North America’s inaugural battery-grade cobalt refinery. The adjacent town, appropriately named Cobalt, could soon see a resurgence in relevance.
Upon completion, the facility will process extracted cobalt rock, transforming it into cobalt sulfate—a crucial component in lithium-ion batteries utilized in various applications, including electric vehicles, smartphones, and military aircraft.
Electra Battery Materials, the project’s proponent, anticipates the plant’s full operation by the end of 2027, with a potential output of 6,500 tonnes of battery-grade cobalt annually—sufficient to cater to approximately one million electric vehicle batteries each year.
Trent Mell, the founder and CEO of the company, emphasized the growing necessity for these essential minerals in modern society, not only for vehicles and energy storage but also for national security considerations.
In the laboratory of the refinery, Graham Kinsman, Electra’s metallurgical lead, is diligently fine-tuning chemical and physical processes to eliminate impurities such as iron and copper from the cobalt.
The refined cobalt product obtained is of high purity, crucial for stabilizing batteries to prevent overheating and prolonging their charge retention capacity.
Despite the historical association of the town of Cobalt with the mineral, the refinery will not locally source mined rock but will import it from overseas.
The region earned its name following the discovery of cobalt during the construction of the Temiskaming and Northern Ontario Railway in 1903, although the primary focus at the time was on silver findings that sparked a significant rush lasting through the 1920s.
Recent efforts by mining companies to prospect for cobalt in the old silver mines have largely been fruitless, with no sustainable veins discovered thus far.
The cobalt supply for the refinery will originate from the Democratic Republic of Congo (DRC), a country that accounts for the majority of global cobalt production. Despite concerns over mining practices in the DRC, Electra is implementing measures to address these issues and ensure responsible sourcing.
Mell is optimistic about the increasing demand for cobalt, particularly in critical sectors like the military, which is expected to surge by tenfold by 2030.
The establishment of refineries like the one in Cobalt is beneficial for Canada, offering the potential to bolster domestic mining operations and reduce reliance on imported cobalt in the future.
China currently dominates the battery-grade cobalt supply chain, with limited refining capacity outside China. Mell aims to emulate China’s successful business model and secure a significant share of the cobalt sulfate market by next year.
The project has garnered significant financial support from government entities, indicating a strategic interest in securing a portion of the cobalt supply chain within North America.
The geopolitical landscape plays a crucial role in shaping the narrative surrounding critical minerals and supply chain security, driving strategic decisions on both sides of the border.
