Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or construction activities.

Milling. For both traditional underground and open pit mining, the rocks may have only a few percent (normally <0.3%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.

Uranium from mining is mostly used as fuel for nuclear power plants. 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. The milling process commonly yields dry powder consisting of natural uranium, " yellowcake," which is sold on ...

The surface miner is a mobile milling machine with a mechanically driven cutting drum. On Wirtgen machinery the drum is located between two sets of individually height adjustable crawler tracks, and a two- stage conveyor system used to directly load trucks. Wirtgen surface miners cut, crush and load the material in one single pass.

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.

Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.
