  Mining. In general, uranium mining is relatively similar to other kinds of mining unless the ore is very high grade. In this case, special mining techniques are used to limit worker radiation exposure and to ensure the safety of the environment and general public.

  There are four main mining methods: underground, open surface (pit), placer, and insitu 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.
