10 million EVs could be powered by lithium hidden in US mine waste

A recent study led by Elizabeth Holley of the Colorado School of Mines reveals that the United States could significantly boost its supply of critical minerals by recovering valuable elements from existing mine waste, currently treated as byproducts. Analyzing 54 active mines across 70 elements, the research estimates that just one year’s worth of U.S. mine waste contains enough lithium to power 10 million electric vehicles and enough manganese for 99 million, far exceeding current domestic demand and imports. Recovering even 1 percent of these byproducts could substantially reduce U.S. reliance on imports, while a 4 percent recovery of lithium alone could eliminate the need for lithium imports entirely. The study highlights specific mines with high potential for various minerals, such as germanium in Alaska’s Red Dog mine and nickel in Montana’s Stillwater and East Boulder mines. The authors argue that the fastest way to increase domestic mineral production is by optimizing existing mining operations through adding recovery circuits for byproducts, which could quickly bring needed minerals to
