Uranium Mining and Extraction from Ore

These processes require significant amounts of acids or bases, the most commonly used being sulfuric acid and sodium carbonate, respectively. Depending on the leaching agents used, the uranium production process also involves several precipitation and purifi ion steps post leaching that were not covered in this work.

Uraninite - Wikipedia

Pitchblende from the Johanngeorgenstadt deposit in Germany was used by M. Klaproth in 1789 to discover the element uranium. All uraninite minerals contain a small amount of radium as a radioactive decay product of uranium. Marie Curie used pitchblende, processing tons of it herself, as the source material for her isolation of radium in 1898.

Uraninite: A radioactive mineral and ore of uranium

In addition to uranium and oxygen, most specimens of uraninite contain varying amounts of several materials. These might include argon, cerium, helium, lead, nitrogen, radium, thorium, yttrium and more. As a matter of trivia, the first helium discovered on Earth was found in a material known as “cleveite,” an impure variety of uraninite.

Uraninite - Wikipedia

Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO 2, but due to oxidation the mineral typically contains variable proportions of U 3 O 8. Additionally, due to radioactive decay, the ore also contains oxides of lead and trace amounts of helium.
