Critical Minerals: Building on Federal Efforts to Advance Recovery and Substitution Could Help Address Supply Risks, Report to the Ranking Member, Subcommittee on Interior, Environment, and Related Agencies, Senate Committee on Appropriations [open pdf - 6MB]
From the Highlights: "The U.S. is heavily reliant on imports of many minerals, such as cobalt and lithium, which are essential for manufacturing advanced technologies (see figure). Supply chains for many of these minerals are also vulnerable to various risks, such as foreign government actions. In 2018, Interior designated 35 minerals and mineral groups whose supply chains are vulnerable to disruption as essential to our nation's economic and national security. GAO [Government Accountability Office] was asked to review federal efforts to advance critical minerals recovery and substitution. This report (1) identifies key challenges affecting efforts to advance critical minerals recovery and substitution in the U.S., and (2) examines the extent to which federal agencies have taken actions to advance recovery and substitution."
