Potential Human Health Effects of Uranium Mining

Potential Human Health Effects of Uranium Mining

Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or construction activities.

The quest for uranium has historical roots in Utah. Initial Utah uranium mining began in the 1870s and 1880s on a small scale, with ore shipped to France and Germany in 1884 for use in the forming of salts and oxides as colorants for ceramics and dyes, in the manufacture of glass and pottery, and as aids in photography and steel plating.

Uranium an overview ScienceDirect Topics

Uranium from processing has generally a 235 U nominal content superior to natural uranium (0.72%) so that the use of reprocessed uranium is a gain not only in mass but also as separative work units (SWU), which represent the energy required to increase the concentration of 235 U above that of natural uranium. For reprocessed uranium to be used in the fuel assemblies that power a commercial ...

Where Does Uranium Come From NEI

Where Does Uranium Come From NEI

Key Facts. Before its use in a nuclear reactor, a series of processing steps converts mined uranium ore into ceramic pellets, which are loaded into fuel rods.; Ore mined from open-pit and underground mines travels to a conventional mill. Solvents or ion exchange processing removes the uranium, resulting in uranium oxide, or yellowcake, which is then filtered, dried and packaged.

Uranium processing Britannica

Uranium processing Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

Five More Things You Didn't Know About Uranium

Uranium glass used to be extremely common, reaching peak popularity from the 1880s to 1920s. Nowadays, though, it has fallen out of widespread use, mainly due to the sharp decline of uranium availability during the Cold War. Most uranium glass found today is considered antique and is highly sought-after by collectors.

Nuclear reactor - Nuclear reactor - Uranium mining and processing: Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope. The mined ore is crushed and the uranium chemically ...
