    Uranium Milling nuclear-power.net

    Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. A conventional uranium mill is a chemical plant, usually built near the uranium mine. Uranium milling extracts uranium using the following process: Milling.

    Uranium — How Is It Mined?

    The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry. This slurry is then mixed with sulfuric acid or an alkaline solution to release the uranium from the host rock. Normally approximately 95 98% of the uranium can be recovered from the host rock.

    Uranium Mining and Milling Wastes: An Introduction

    If, for example, 90% of the uranium contained in an ore with 0.1% grade was extracted during the milling process, the radiation of the tailings stabilizes after 1 million years at a level 33 times that of uncontaminated material. Due to the 4.5 billion year half-life of uranium-238, there is only a minuscule further decrease.
