Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production.

The former mill processed uranium and other ores at the site between 1911 and 1957 and provided uranium for the government national defense programs. Standard Chemical operated the site as a radium extraction plant from 1911 to 1922. Later, Vitro Corporation of America acquired the property and processed ore to extract radium and uranium

Uranium ore concentrate (UOC) is a general term to describe the final product of uranium mining and milling, although the term "yellowcake" is still loosely used. In fact, UOC may be yellow (eg, ammonium diuranate, uranyl peroxide), dark greenblack, grey (U 3 O 8), (Fig. ), and sometimes orange. Download : Download fullsize image ...

A raised uranium ore slurry pipe connects the crushing and grinding mill, located adjacent to Mine 1, to the plant. Satellite imagery offers few observable indicators of the plant's operational status. Dust and chemical stains around the roof vents of a number of the buildings reveal use but change little between coverage.

A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

Uranium Conversion. After the uranium ore concentrate is produced at the mill (where it becomes uranium oxide or "yellow cake"), it is packaged in 55 gallon drums and sent to the uranium conversion plant. At the conversion facility, the yellow cake is processed and is then reacted with fluorine to create uranium hexafluoride (UF 6).Uranium, in the chemical form of UF 6, is suitable for use in ...

Union Carbide Corporation began milling the ore in 1924 at what is now referred to as the Old Rifle mill site. The plant was shut down in 1932 due to a poor market, but reopened in 1942 to produce vanadium for the war effort. The mill was left abandoned along with several million tons of unprocessed ore.

Uranium Ore is hauled by truck to the mill site, where it is weighed and a grab sample taken for moisture. Truck loads from each respective ore supplier are then dumped on a stock lot until 150200 tons are accumulated at which time it is delivered to a 50ton receiving hopper for passage through the crushing and sampling plant.

The product of uranium mining is normally uranium oxide concentrate U 3 O 8 which is shipped from the mines in 200litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings.
