Milling. Uranium ore is crushed and processed in uranium mills, located at or near the mines, to extract uranium using chemical processes. A fine powder, called "yellowcake", is the resulting uranium concentrate product and is packed in 55 gallon ringsealed drums containing approximately onehalf tonne of yellowcake. Mine tailings are ...

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.
