Because uranium ore emits radon gas, uranium mining can be more dangerous than other underground mining, unless adequate ventilation systems are installed. During the 1950s, many Navajos in the U.S. became uranium miners, as many uranium deposits were discovered on Navajo reservations.
Uranium mining is the process of extraction of uranium ore from the ground. Over 50,000 tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were ...
Uranium tailings or uranium tails are a radioactive waste byproduct of conventional uranium mining and uranium enrichment. They contain the radioactive decay products from the uranium decay chains, mainly the U-238 chain, and heavy metals. Long-term storage or disposal of tailings may pose a danger for public health and safety.
A uranium producer has agreed to temporarily pause the transport of the mineral through the Navajo Nation after the tribe raised concerns about the possible effects that it could have on the ...
Beyond naturally occurring uranium, mining, phosphates in agriculture, weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment. [ 1 ] In the natural environment, radioactivity of uranium is generally low, [ 1 ] but uranium is a toxic metal that can disrupt normal functioning of the kidney, brain, liver ...
At around 5:30 am on July 16, 1979, a previously identified crack opened into a 20-foot-breach (6.1 m) in the south cell of United Nuclear Corporation's Church Rock temporary uranium mill tailings disposal pond, and 1,100 short tons (1,000 t) of solid radioactive mill waste and about 93 million US gallons (350,000 m 3) of acidic, radioactive tailings solution flowed into Pipeline Arroyo, a ...
The uranium is legally owned by the Australian Government, and is sold internationally, having a large effect on the Australian economy. The mining has been controversial, due to the widespread publicity regarding the potential danger of nuclear power and uranium mining, as well as because of objections by some Indigenous groups. [1]
Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
