Radioactive Waste From Uranium Mining and Milling

Mar 02, 2020· 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 nuclear-power.net

Due to the very low concentration of uranium in the rock, immense amounts of rock have to be moved and processed in order to get a few kilograms of natural uranium. This results in enormous heaps. Due to high amounts of material, milling is generally carried out close to a uranium mine. Leaching. After milling, a fine slurry is leached in sulfuric acid (or sometimes a strong alkaline solution) to allow the separation of uranium

Uranium mining by country Wikipedia

In Hungary, uranium mining began in the 1950s around Pécs to supply the country's first atomic plant in Paks. A whole district was built for the mining industry on the outskirt of Pécs, for which the name Uránváros (Uranium city) was given. After the fall of communism, uranium mining was gradually given up because of the high production costs.
