CRITICAL MINERALSThe Year the US. Doubled Down on Critical Minerals
President Donald Trump spent most of 2025 hacking away at large parts of the federal government. One tiny corner of regulation, however, has actually grown under Trump: the critical minerals list. The list of metals became a top priority under Trump. But what even are they?
President Donald Trump spent most of 2025 hacking away at large parts of the federal government. His administration fired, bought out, or otherwise ousted hundreds of thousands of federal employees. Entire agencies were gutted. By so many metrics, this year in politics has been defined more by what has been cut away than by what’s been added on.
One tiny corner of regulation, however, has actually grown under Trump: the critical minerals list. Most people likely hadn’t heard of “critical minerals” until early this year when the president repeatedly inserted the phrase into his statements, turning the once obscure policy realm into a household phrase. In November, the U.S. Geological Survey quietly expanded the list from 50 to 60 items, adding copper, silver, uranium, and even metallurgical coal to the list. On Monday, South Korean metal processor Korea Zinc announced that the federal government is investing in a new $7.4 billion zinc refinery in Tennessee, in which the Department of Defense will hold a stake.
But what even is a critical mineral?
The concept dates back to the first half of the twentieth century, especially World War II, when Congress passed legislation aimed at stockpiling materials vital to the United States’ well being. President Trump established the critical minerals list in 2018, with the defining criteria being that any mineral included be “essential to the economic and national security of the United States” and have a supply chain that is “vulnerable to disruption.” A mineral’s presence on the list can convey a slew of benefits to anyone trying to extract or produce that mineral in the U.S., including faster permitting for extraction, tax incentives, or federal funding.
As Grist explored in its recent mining issue, critical minerals are shaping everything from geopolitics to water supplies, oceans, and recycling systems. If there is to be a true clean energy transition, these elements are key to it. Metals such as lithium, cobalt, and nickel form the backbone of the batteries that power electric vehicles. Silicon is the primary component of solar cells and rare earth magnets that help make wind turbines function. Not to mention computers, microchips, and the multitude of other things that depend on critical minerals.
