資料簡介

2017年,美國非燃料礦產(chǎn)總產(chǎn)值估計為752億美元,比2016年修訂后的708億美元增長6%。金屬生產(chǎn)的估計價值增加了12%,達到263億美元。價格上漲導(dǎo)致一些金屬商品價值增長超過35%(鈷、鎂金屬和鈀)。盡管如此,美國一些金屬礦山和加工設(shè)施在2017年仍然閑置,包括印第安納州、密蘇里州和華盛頓的三家一級鋁冶煉廠;猶他州的一家海綿鈦工廠;猶他州的一家副產(chǎn)品釩生產(chǎn)工廠。然而,分別于2016年底和2017年在內(nèi)華達州和南卡羅來納州開設(shè)了新的金礦,密歇根州和明尼蘇達州的鐵礦重啟或全年運營。工業(yè)礦產(chǎn)總產(chǎn)值489億美元,比2016年增長3%。其中,230億美元是骨料生產(chǎn)(建筑用砂、礫石和碎石)。石油和天然氣鉆探活動的增加導(dǎo)致一些工業(yè)礦物商品的產(chǎn)量增加。建筑活動的有限增長導(dǎo)致一些工業(yè)礦物的生產(chǎn),特別是用于基礎(chǔ)設(shè)施和住宅建設(shè)的礦物,在2017年基本保持不變。

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.
