2021-6-14  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. Trucks deliver uranium ore to the mill,
