Each chapter of the 2018 edition of the U.S. Geological Survey (USGS) Mineral Commodity Summaries (MCS) includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and resources. The MCS is the earliest comprehensive source of 2017 mineral production data for the world. More than 90 individual minerals and materials are covered by two-page synopses.
In 2017, the estimated value of total nonfuel mineral production in the United States was $75.2 billion, a 6% increase from the revised total of $70.8 billion in 2016. The estimated value of metals production increased 12% to $26.3 billion. Higher prices contributed to some metal commodity values increasing more than 35% (cobalt, magnesium metal, and palladium). Despite this increase, some U.S. metal mines and processing facilities remained idle in 2017, including three primary aluminum smelters in Indiana, Missouri, and Washington; a titanium sponge facility in Utah; and a byproduct vanadium production facility in Utah. However, new gold mines opened in late 2016 and 2017 in Nevada and South Carolina, respectively, and iron ore mines in Michigan and Minnesota restarted or operated for the full year. The total value of industrial minerals production was $48.9 billion, a 3% increase from that of 2016. Of this total, $23 billion was aggregates production (construction sand and gravel and crushed stone). Increased oil and natural gas drilling activity resulted in increased production of some industrial mineral commodities. Limited growth in construction activity resulted in the production of some industrial minerals, especially those used in infrastructure and residential construction, to remain essentially unchanged in 2017.
