Mill tailings contain smaller concentrations of uranium, other naturally radioactive waste products such as radium and thorium, and process chemicals. The milled uranium is then processed to further purify it and prepare a portion for manufacture into nuclear reactor fuel or weapons material.

Fact sheet: uranium mining and milling

Uranium milling Milling is the process used to extract the uranium from the mined ore or from the mining solution used in-situ leaching. The first stage of milling is to crush the rock and ore until it is roughly the grain size of sand. Sulphuric acid is then used to leach the uranium from the crushed rock.

Uranium Processing

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 U.S. gallon ring-sealed drums containing approximately one-half tonne of yellowcake.
