2017年矿产商品摘要(2017)mcs2017(2017)

2016年，美国非燃料矿产总产量估计值为746亿美元，较2015年修订后的734亿美元略有增加。建筑活动的增加促进了工业矿物产量的增加，特别是用于基础设施和住宅建设的矿物。虽然年初价格相对较低，但一些金属，特别是一些贵金属的价格开始出现上涨趋势。然而，美国生产的大多数金属产量的减少，导致了金属生产价值的全面下降。2016年，美国多个金属矿山和加工设施被闲置或永久关闭，包括密歇根州和明尼苏达州的铁矿；印第安纳州、密苏里州和华盛顿州的三个一级铝冶炼厂；北卡罗来纳州的一个二级锌冶炼厂；犹他州的一个钛海绵设施，这是美国唯一的此类设施；以及弗吉尼亚州的钛矿业务。此外，5月份，石油和天然气钻井的周平均钻机数量达到了自上世纪40年代首次有记录以来的最低水平。钻探活动的减少导致钻探部门使用的一些工业矿物产品产量下降。

In 2016, the estimated value of total nonfuel mineral production in the United States of $74.6 billion was a slight increase from the revised total of $73.4 billion in 2015. Increased construction activity spurred increased production of industrial minerals, especially those used in infrastructure and residential construction. Although starting the year relatively low, prices for several metals, especially for some of the precious metals, began to trend upward. Decreased production of most metals produced in the United States, however, contributed to an overall decline in the value of metal production. Several U.S. metal mines and processing facilities were idled or closed permanently in 2016, including iron ore mines in Michigan and Minnesota; three primary aluminum smelters in Indiana, Missouri, and Washington; one secondary zinc smelter in North Carolina; a titanium sponge facility in Utah, the only such facility in the United States; and titanium mineral operations in Virginia. In addition, in May, the weekly average rig count for oil and gas drilling reached its lowest level since the 1940s when that measurement was first recorded. The reduced drilling activity resulted in decreased production of some industrial mineral products used in the drilling sector.
