Uranium mining in the United States - Wikipedia

Uranium mining in the United States produced 173,875 pounds (78.9 tonnes) of U 3 O 8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds (656.8 tonnes) of U 3 O 8 and the lowest US annual production since 1948. The 2019 production represents 0.3% of the anticipated uranium fuel requirements of the US's nuclear power reactors for the year.

Weight-percent of uranium or U 3 O 8 contained in the ore in the deposit (in situ). Mine: Waste/Ore Ratio At conventional uranium mines, overburden and waste rock has to be removed to get access to the uranium ore. The waste-to-ore ratio can range between 1 and 5 for underground mines and between 1 and 60 for open pit mines.

Uranium (Nuclear)

Because less than one percent of uranium ore contains uranium-235, the form used for energy production, uranium must be processed to increase its concentration. This process—called enrichment—increases the percentage of uranium-235 from 0.7 to three to five percent, the percentage required for reactor fuel. It typically takes place at a gaseous

The uranium implications were not mentioned, but assuming the same ore as today, it would mean about 5000 t U 3 O 8 (4200 tU) per year from 2018 and some 9400 t U 3 O 8 (8000 tU) per year in mid-2020s. In July 2016 the company confirmed that it would now focus on underground development only and not pursue the earlier open pit plan.

Uranium Ore - an overview ScienceDirect Topics

The percentage of 235 U in natural uranium ore slowly changes with time, with the current content being 0.72% (Table 4.1). As the half-life of 235 U is shorter than that of 238 U, billions of years ago this ratio was much higher at levels enabling self-sustaining fission reactions to occur naturally.

Only rarely do the ores contain more than 1% uranium or vanadium; most of the ores average about 0.2% uranium and less vanadium. The first 3 million tons of ore shipped from the mine averaged 0.23 percent U 3 O 8 and 0.13 percent V 2 O 5 (1958 data). The ore bodies are typical "roll-front" deposits, localized in old stream channels.
