It seems that all of a sudden there is talk of mineral shortages and two metals which are thought to be plentiful in the Earth's crust, nickel and zinc, have been added to the list of minerals now deemed critical to the United States, a list recently updated by the U.S. Geological Survey.
Partly, the concern is that the United States is not producing enough of its own nickel and zinc to rest easy over the availability of these metals on world markets. Nickel's new status stems in part from its emerging role in electric vehicle batteries. There is only one operating U.S. nickel mine. The situation with zinc is less concerning since there are 14 mines and three smelters.
There has long been concern about Rare Earth Elements (REEs) crucial to the computer and renewable energy infrastructure. Part of the concern is China's domination of the production of these minerals. Chinese mines supplied 55 percent of all REEs mined worldwide in 2020 and its REE refineries produced 85 percent of all refined products.
