Minerals critical to the U.S. economy are identified in a new report funded by the U.S. Geological Survey (USGS) and the National Mining Association.
The report, issued by the National Research Council (NRC) of the National Academies, identifies two mineral families and three individual minerals that are difficult to duplicate and for which supply faces significant risk of disruption. The NRC report also provides a new way to assess how critical individual minerals are to the U.S. economy, called the critical matrix.
Any mineral could at some point become critical to the economy or national security, depending on its uses and availability. The most critical at present are platinum group metals, rare earth elements, indium, manganese, and niobium, which are used to make catalytic converters, LCD TVs, pacemakers, and other products.
This study assesses the Nation's minerals information and research needs and makes recommendations for meeting those needs. Awareness about nonfuel mineral issues is a crucial first step in the discussion and planning required to ensure that critical nonfuel mineral resources will be available and affordable to meet demand for current and emerging needs.
"Natural resources play a fundamental role in our economy and quality of life, and it's important to address the adequacy of supply, quality, and short and long term availability of these resources," said Kathleen Johnson, Coordinator of the USGS Mineral Resources Program. "The USGS believes this report is an important contribution to the ongoing discussion."
