    Uranium processing Britannica

    Uranium processing, preparation of the ore for use in various products. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals

    Uranium - Wikipedia

    Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

    Uranium processing - Canadian Nuclear Association

    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 the在 cna.ca 上查看更多信息
