What is Uranium How Does it Work   World Nuclear

What is Uranium How Does it Work World Nuclear

Uranium ore can be mined by underground or opencut methods, depending on its depth. After mining, the ore is crushed and ground up. Then it is treated with acid to dissolve the uranium, which is recovered from solution. Uranium may also be mined by in situ leaching ISL, where it is dissolved from a porous underground ore body in situ and ...

Uranium How Is It Mined

Uranium resources can be extracted from the ground in three ways open pit, underground, and insitu leach ISL. Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5.

In a mill, uranium is extracted from the crushed and groundup ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium. The uranium is then removed from this solution and precipitated. After drying and usually heating it is packed in 200litre drums as a concentrate.
