According to the US Geological Survey's Mineral Commodity Summaries 2014 report, the US produced $74.3 billion worth of minerals in 2013, down slightly from $75.8 billion in 2012. The report reveals that the net exports of mineral raw materials and old scrap contributed an additional $15.8 billion to the US economy.
"To put this in context, the $90.1 billion value of combined mined, exported, and recycled raw materials is more than five times greater than the 2013 combined net revenues of Internet titans: Amazon, Facebook, Google, and Yahoo," USGS Mineral Resources Program Coordinator Larry Meinert said in a statement. "This illustrates the fundamental importance of mineral resources to the nation’s economy, technology, and national security."
The drop in value was not due to lower production – in fact, production increased for most industrial mineral commodities and remained stable for most metals. The drop in metals prices resulted in the reduced value of US mineral production.
