<p>The United States Geological Survey has revealed an updated list of 50 critical minerals that the North American country needs for economic and national security. Replacing the initial 2018 version, the new list has added 15 new minerals, while removing four others. Most of the new additions come from differentiating specific rare earth elements and platinum group elements as individual entries rather than grouping the commodities. Base metals nickel and zinc are also new entries on the list.
