A facility near Cobalt, Ont., has been tapped to be the home of North America's first battery-grade cobalt refinery. Projected to be fully operational by late 2027, the plant will import and process mined cobalt, experts say it could bring Canada into an industry dominated by China. A former silver mining area in northern Ontario has been tapped to be the home of North America's first battery-grade cobalt refinery. When completed, the facility will process mined cobalt rock, refining it into cobalt sulfate, an essential ingredient in lithium-ion batteries used in everything from electric vehicles. And smartphones to fighter jets. Electra Battery Materials, the company behind the project, says the plant will be fully operational by the end of 2027. And could produce 6,500 tonnes of battery-grade cobalt, enough to supply about one million electric vehicle batteries per year.
