When first mined, Uranium isn’t functional for nuclear energy or military use; it needs to be enriched to ≈20% for power and ≈85% for military use. The enrichment process requires the mined uranium ore to be processed in a mill. Energy Fuels own the only ‘fully-licensed and operating conventional uranium mill in the United States.’ (4).

Worldwide, the mining of uranium has generated 938 × 10 6 m 3 of mill tailings. The radioactivity of these tailings depends on the grade of ore mined and varies from less than 1 Bq/g to more than 100 Bq/g. The most common mode of disposal is near-surface impoundment in the vicinity of the mine or mill.
