    For the most part, the ores are not subjected to dressing however, radiometric sorting based on the gamma radiation of radium, which always accompanies uranium, is used on a limited scale. In general, the ores are subjected to either acid leaching sulfuric acid and, sometimes, nitric acid or carbonate leaching.

    In a conventional mill, the first step is grinding the ore to a size suitable for leaching out the uranium. Ore characteristics and the leaching process dictate the degree to which ore must be ground. For the acid leaching of sandstone ores, the ore is ground to the natural grain size. Alkaline leaching requires much finer grinding.
