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

The precipitated slurry is pumped to a 12′ x 16′ propeller agitated holding tank and thence split to a 24″ 20-frame Burwell filter press and a 36″ 20-frame standard filter press. Filtrate goes to waste and the uranium concentrate (yellow cake) assaying 79% U3O8 drops to pan dryers. After drying to 4% moisture it is packed in drums and ...
The most common form of U 3 O 8 is yellow cake, a solid named for its characteristic color that is produced during the uranium mining and milling process. UO 2 is a solid ceramic material and is the form in which uranium is most commonly used as a nuclear reactor fuel . At ambient temperatures, UO 2 will gradually convert to U 3 O 8.
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).All isotopes of radium are highly radioactive, with the most ...

Waste retention Storage system for liquid and solid wastes generated by the system uranium or thorium mining and milling process. Liquid wastes:
Over two-thirds of the world's production of uranium from mines is from Kazakhstan, Canada and Australia. An increasing amount of uranium, now over 50%, is produced by in situ leaching. After a decade of falling mine production to 1993, output of uranium has generally risen since then and now meets almost all the demand for power generation.

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.
The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which the fuel is used during reactor operation, and steps in the back end, which are necessary to safely manage, contain, and either reprocess or dispose of ...
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 Mining In the last fifty years uranium has become one of the world's most important energy minerals. It is used almost entirely for making electricity, though a small proportion is used for the important task of producing medical isotopes.
Fig. 1 shows the points in the uranium conversion process where spent NaF adsorbents, sludge-like wastes, and residue wastes are generated. UF 4 was produced from a solution, in which yellow cake was dissolved as uranous ions in a reaction bath. A portion of UF 4, which could not be transported because of solidification, remained as a blockish residue waste in the reaction bath.
The solid waste remaining after recovery of uranium in a processing plant are the tailings, consisting of everything that was in the ore except the extracted uranium. The main radioactive materials remaining are those from the uranium decay series, mainly thorium-230 and radium-226.
