Arizona produced $7.38 billion of non-fuel minerals in 2007, the highest of any state, and equal to 10.85% of all U.S. production, according to the annual Mineral Commodities Summaries 2008 released by the USGS. Nevada had the second highest production at $5.21 billion.
The principal minerals produced in Arizona, in order of value, were copper, molybdenum concentrates, sand and gravel (construction), cement (portland), and lime.
This is the third year in a row that Arizona has been #1.
Arizona's 2007 production value was up almost exactly 10% over 2006.
