Characteristics of Uranium and Its Compounds

8 is the most stable form of uranium and is the form found in nature The most common form of U 3O 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.

Gaseous Diffusion

Hence the first destination of uranium oxide concentrate from a mine is a conversion plant where it is purified and converted to uranium hexafluoride The UF 6 is then fed to an enrichment plant 6 which increases the proportion of the fissile U 235 isotope about five or six fold from the 0.7 of U 235 found in natural uranium.

Conventional Uranium Mills

A conventional uranium mill is a chemical plant that extracts uranium using the following process Trucks deliver uranium ore to the mill where it is crushed into smaller particles before being extracted or leached In most cases sulfuric acid is the leaching agent but alkaline solutions can also be used to leach the uranium from the ore.

Environmental Impacts of Uranium Mining

Uranium enrichment

Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium 235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel the Canadian designed CANDU the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel.
