Nuclear fuel cycle' Extractingg uranium from its ores

Milling operations After the uranium ore is mined, the next step in the nuclear fuel cycle is to chemically extract the uranium from the ore and produce a partially refined product with a uranium content of at least 65%. This material is normally termed yellow-cake. Uranium milling is based primarily on hydrometallurgical operations such as

Vanadium is usually produced as the byproduct or coproduct of another element, such as iron, uranium, molybdenum, or phosphorus. In the United States, vanadium is recovered: (1) as a principal mine product, (2) as a coproduct from carnotite ores, and (3) from ferrous slag as a byproduct in the production of elemental phosphorus.

Acid Leaching of Uranium

Acid leaching has been used in the uranium milling industry since the mid-forties and has accounted for a majority of the production since that time. It is preferred over carbonate leaching because of its greater efficiency in recovering uranium. Consequently much research has been done on the factors which influence the kinetics of the oxidation of uranium, as well as those which influence ...

Uranium - Wikipedia

Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
