Uranium is a chemical element with the symbol U and atomic number 92 It is a silverygrey metal in the actinide series of the periodic tableA uranium atom has 92 protons and 92 electrons, of which 6 are valence electronsUranium is weakly radioactive because all isotopes of uranium are unstable; the halflives of its naturally occurring isotopes range between 159,200 years and 45 billion yearsIt consists of uranium oxides, silicates and hydrates Its yellow color is often an indication that uranium minerals are nearby This specimen consists of a mixture of gummite (yellow), uraninite (black), and zircon (brown) It measures approximately 87 x 71 x 20 centimeters and is from the Ruggles Mine in Grafton County, New HampshireUraninite: A radioactive mineral and ore of uranium

After mining, uranium ore is processed into yellowcake, a type of uranium concentrate powder obtained from leach solutions Yellowcake is then converted into a form that can be enriched to fuel grade concentration, and ultimately fabricated into fuel rod assemblies for electrical generationHowever, when the deposits comprise uranium fluoride hydrolysis products, such as uranyl fluoride UO 2 F 2 and its hydrates, removal of these deposits with IF 7 alone is less than complete A reacting gas mixture of a brominating agent, such as bromotrifluoromethane (CBrF 3), dibromodifluoromethane (CBr 2 F 2), and a fluorinating agent, such as IF 7, BrF 3, or F 2, can remove these deposits [395]Uranium Oxide an overview | ScienceDirect Topics
Uranium Mining Overview World Nuclear Association
Most of the uranium ore deposits at present supporting these mines have average grades in excess of 010% of uranium – that is, greater than 1000 parts per million In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average gradeYellowcake (also called urania) is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium oresIt is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichmentYellowcake concentrates are prepared by various extraction and refining methods, depending on the types of oresYellowcake Wikipedia

homework Does Uranium ore count as a mixture
The main uranium ore is pitchblende, or uraninite, which is primarily composed of $\ce{UO2}$ $\ce{UO2}$ is ionically bonded together in a crystal structure and so is definitely a compound and not a mixturePotassium Permanganate – For the system tested, the use of permanganate and air did not improve the uranium extraction of that obtained with air alone CopperAmmonia Complex – The use of copperammonia in the range of 2 pounds of copper sulfate and 8 pounds of NH3 per ton of ore did not enhance the extraction of uranium for the ores testedOxidation and Cyanide as an Oxidation Catalyst in Pressure
