What is Uranium? How Does it Work
Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum. Uranium occurs in seawater, and can be recovered from the oceans. Uranium was discovered in 1789 by Martin Klaproth, a German chemist, in the mineral called pitchblende.

Uranium Mining Overview
Uranium Mining Overview. (Updated August 2023) In the last 60 years uranium has become one of the world's most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.
Hot Rocks: A Rockhound's Guide to Radioactivity
During the late 1940s and early 1950s, Colorado, Utah, and New Mexico hosted what was called the " Great Uranium Rush " (Rock & Gem, April 2017), the last mineral rush in which individual prospectors had a chance to strike it rich. The quest was for, in the parlance of that era, "hot rocks"— rocks emitting elevated levels of ...

Uranium and Depleted Uranium
Uranium was discovered by Martin Klaproth, a German chemist, in 1789 in the mineral pitchblende, and was named after the planet Uranus. It occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum and about 40 times as common as silver.
Uranium in natural waters and the environment
The concentrations of U in natural waters are usually low, being typically less than 4 μg/L in river water, around 3.3 μg/L in open seawater, and usua…
The 10 Biggest Uranium Reserves In The World
Uranium, a chemical element with a U symbol and an atomic mass equal to 238 u, has an atomic number 92. Highly reactive in energy-creating processes, uranium is far more common than silver and gold, and may prove to be far more practical than any 'precious' mineral in meeting the long-term needs of our planet's human population.
Uranium | Toxic Substances | Toxic Substance Portal | ATSDR
Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air, and water, and it occurs in nature in the form of minerals – but never as a metal. Uranium metal is silver-colored with a gray surface and is nearly as strong as steel. Natural uranium is a mixture of three types or isotopes called U ...
