Vanadium for batteries can be extracted from Canada’s oilsands and potentially double world production

Vanadium is a largely obscure metal often used in making steel. It retains its hardness at high temperatures, so it’s ideal for making drill bits, engine turbines and other parts that generate heat. In the oilsands, Vanadium is one of the metals that comes out of the ground with bitumen. The concentration is quite low: …
