• Uranium is a silver-gray metallic chemical element.
• Uranium, not as rare as once thought, is now considered to be more plentiful than mercury, antimony, silver, or cadmium, and is about as abundant as molybdenum or arsenic.
• It occurs in numerous minerals such as pitchblende, uraninite, carnotite, autunite, uranophane, and tobernite. It is also found in phosphate rock, lignite, monazite sands, and can be recovered commercially from these sources.
• Uranium is located in the earth's crust. However, it is not evenly spread, so it is only mined in the most profitable mineral deposits.
• Vast amounts have to be mined, since most rock contains very little uranium ore (below 0.5%).
• Radon gas and contaminated water leak from giant waste dumps and threaten the health of human and surrounding ecosystems.
• Large amounts of contaminated water can seep into the ground water and further contaminate rivers.
• Underground and surface workers are exposed to radio active substances and suffer the risks of lung and other cancers.
• Canadian uranium ore comes from open-pit operations.
• Once mined, the ore is trucked or pumped as a slurry to the milling facility.
•  At the mill, the ore is finely ground and mixed in either a highly acidic or alkaline solution to extract the uranium.
• The current uranium market is mainly a reflection of several partly interconnected economic, parameters: reactor-related uranium demand, supply, and uranium prices.
• Uranium demand is based on nuclear electricity generating capacity, whose growth had been vastly overestimated in the past.
• The pricing of uranium has always been relatively opaque, because there is no terminal market quotation and full details of individual contracts are seldom released.
• The purification of crude uranium recovered from its ores at plant-scale using tributylphosphate (TBP).
• TBP extraction technology and processes are applied world-wide for the purification of crude uranium and also thorium.
• ISL technology recovers uranium using two alternative chemical leaching systems —acid and alkaline.
• Acid leach is the more widely employed and has historically produced a majority of the world’s ISL production.
• Liquid—liquid solvent extraction technology is used in numerous industrial processes.
• Uranium is used as a colorant in uranium glass, producing orange-red to lemon yellow hues.
• It was also used for tinting and shading in early photography.
• Uranium is of great importance as a nuclear fuel.
• Uranium in the U.S.A. is controlled by the U.S. Nuclear Regulatory Commission.
• Crystals of uranium nitrate are triboluminescent.
