The US Geological Survey just released their Mineral Commodity Summaries 2017, detailing mineral production in the U.S. in 2016. How did Arizona fare?

“In 2016, 11 States each produced more than $2 billion worth of nonfuel mineral commodities. These States were, in descending order of production value, Nevada, Arizona, Texas, California, Minnesota, Florida, Alaska, Michigan, Wyoming, Missouri, and Utah (table 3).”
Arizona' total non-fuel mineral production in 2016 was $ 5,560 million, 7.45% of U.S. total. Principal minerals, in order of value included: copper, sand and gravel (construction), molybdenum concentrates, cement (portland), stone (crushed). Once again, Arizona led the U.S. in copper production, with significant increase in copper production at Freeport-McMoRan's Morenci Mine.
In terms of gemstones production, Arizona tracked second in the U.S. behind Idaho. Arizona placed 7th in sand and gravel for construction production.
