Critical minerals play an essential role in modern technologies, and a domestic supply is essential for national security. Elizabeth Holley, associate professor of mining engineering at Colorado School of Mines, discusses how domestic supplies might be increased by recovering critical minerals from the byproducts of existing mining sites.
We cover what critical minerals are and how they are defined by different agencies, what and how much we produce in the US versus foreign sources, and how we might eliminate the reliance on foreign imports by collecting the byproducts of existing domestic mining operations.
