Uranium surface mining flowchart - greenrevolutionorgin.Uranium mining uranium mining is the process of extraction of uranium ore from the groundif the uranium is too far below the surface for open pit mining, an underground mine might be used with tunnels and shafts dug to access and remove uranium.
There are four main mining methods underground, open surface pit, placer, and in-situ mining.Underground mines are more expensive and are often used to reach deeper deposits.Surface mines are typically used for more shallow and less valuable deposits.Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
