Last year, the U.S. Geological Survey (USGS) released its 2022 list of 50 minerals that are essential to the function of our society, especially the economy and national security. Whether it’s indium for LCD screens and aircraft wind shielding, cobalt for iPhones, uranium for nuclear reactors and munitions, rare earth elements for wind turbine magnets, lithium for rechargeable batteries, or tantalum for electronic components, if we do not have an ample supply, bad things will happen.
