Uranium Ore (Carnotite). Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining.The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

Uranium Milling Overview - coloradonuclearatlas.org

Dissolved or leached uranium is concentrated, purified, and dried to become the final product: yellowcake. After milling, other companies buy the uranium and enrich it in order to use the material as nuclear fuel. The milling process creates byproduct materials. This sandy waste is often referred to as tailings and contains heavy metals and radium.
