uranium milling refining and conversion

Cameco U101 Refining & Conversion

For light water reactors that require higher concentrations of U 235, the next step is conversion to uranium hexafluoride (UF 6), a chemical form suitable for enrichment.During this conversion process, the UO 3 is combined with fluorine compounds to create UF 6.UF 6 is the only uranium compound that can exist as a gas, a liquid or a solid, depending on pressure and temperature.

Uranium MillingRefining & ConversionEnrichmentFuel ManufacturingAfter mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution, which is then separated from the other minerals, which remain solid. The uranium-rich solution is then purified through a solvent extraction proces.

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

Cameco U101 Milling

Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper, gold or nickel.

MiningEnrichmentFuel FabricationUranium mines operate in some twenty countries, though about half of world production comes from just ten mines in six countries, in Canada, Australia, Niger, Kazakhstan, Russia and Namibia.At conventional mines, the ore goes through a mill where it is first crushed. It is then ground in water to produce a slurry of fine ore particles suspended in the water. The slurry is leached with sulphuric acid to dissolve the uranium oxides, leaving the remaining rock and other minerals undissolved, as.
