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 extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.

Processing Uranium. Ore from in-situ uranium mines is already in a liquid form as it has been pumped out of the ground. However, ore from open-pit mines is first crushed and mixed with water and then added to large tanks of acid. Because uranium dissolves easily, in solution it becomes separated from other minerals and elements, which remain solid.
