1st Quarter 2013

U.S. production of uranium in the first quarter 2013 was 1,147,031 pounds U₃O₈, up 20 percent from the previous quarter and up 6 percent from the first quarter 2012. During the first quarter 2013, U.S. uranium was produced at six U.S. uranium facilities.

U.S. Uranium Mill in Production (State)

1. White Mesa Mill (Utah)

U.S. Uranium In-Situ-Leach Plants in Production (State)

1. Alta Mesa Project (Texas)
2. Crow Butte Operation (Nebraska)
3. Hobson ISR Plant/La Palangana (Texas)
4. Smith Ranch-Highland Operation (Wyoming)
5. Willow Creek Project (Wyoming)

Table 3 now includes planned heap leach facilities Gas Hills and Sheep Mountain. Heap leaching is the separation, or dissolving-out from mined rock, of the soluble uranium constituents by the natural action of percolating a prepared chemical solution through mounded (heaped) rock material. The mounded material usually contains low grade mineralized material and/or waste rock produced from open pit or underground mines. The solutions are collected after percolation is completed and processed to recover the valued components.

Final 2012 total

U.S. uranium concentrate production totaled 4,145,647 pounds. This amount is 4 percent higher than the 3,990,767 pounds produced in 2011.
